test: fix hugepage file handling in EAL flags autotest

Before 18.05, DPDK could not release memory back to the system
neither at runtime nor before shutting down. Over the course of
18.05 up to 18.11, code was introduced to release memory at
runtime, as well as an rte_eal_cleanup() function that is supposed
to release all EAL-allocated memory before shutting down DPDK.

When 3f9e31d71d63 ("test: clean up on exit") was introduced, the
test application started to use rte_eal_cleanup() to release all
used memory after execution. However, the EAL flags autotest
still relies on the old behavior of leaving stuff behind in the
hugetlbfs.

The fix is twofold. First, the test to check for leftover files
in hugetlbfs is no longer valid as it is, because test application
now removes all files from hugetlbfs after exit. However, if we
use the --legacy-mem option, then old behavior of leaving files
in hugetlbfs after execution is restored. So the first fix is to
add --legacy-mem to all the tests that expect files in hugetlbfs
to be leftover.

However, we also need to test if default memory mode *doesn't*
leave any files behind, so we also extend the test to check for
these scenarios as well. So, both memtest1 and memtest2 are run
in legacy and default mem modes, and are checked for any leftover
files that are or are not supposed to be there.

provides the buffer with at least double of the data size.

However there is no way for VMs to know this limitation. When

next to the VM data to be processed, and further cause problems

To fix the problem the user should avoid enabling the zero copy

The tc flower filter rules are used to control E-switch from

offload the skip_sw flag should be specified while applying the

is set by design. Currently this regards VXLAN tunneling rules,
which are applied to special VXLAN virtual devices. Albeit these
rules are applied with skip_sw flag reset kernel tries to
perform hardware offload. If kernel succeeded the in_hw flag
is set in rule properties and application should check this
flag to get know whether the applied rule is actually hardware
offloaded.

This patch prepares for the rule flags query and check in_hw flag.
The driver checks only the rules with skip_sw flag reset, so we
need to test the actual flags of rule is being applied. The pointer
to flags field into translated rule is introduced and flags are
tested directly in the rule body. It is more reliable than save and
check flags copy.

Also patch swaps the flow_tcf_apply() and flow_tcf_remove(),
we are going to call flow_tcf_remove() from flow_tcf_appy() if
no in_hw flag set found in applied rule.
