This commit addresses a case of RSS and non RSS flows mixture.
In the corrupted code, if a non-RSS flow is destroyed, it has an eBPF map

RSS entry 0 from eBPF map.
To fix this issue, add an offset to the real index during a KEY_CMD_GET
operation, and subtract this offset during a KEY_CMD_RELEASE operation, in
order to restore the real index.
Thus, if a non RSS flow is falsely trying to release map entry 0 - The
offset subtraction will calculate the real map index as an
out-of-range value, and the release operation will be silently ignored.

The agreement is to keep two exceptions enabled by default in 18.02:
Rx CRC strip and Tx fast free.
Motivation:
Some PMDs such at the mlx4 may not implement all the offloads.
After the offload API rework assuming no offload is enabled by default,
commit ce17eddefc20 ("ethdev: introduce Rx queue offloads API")
commit cba7f53b717d ("ethdev: introduce Tx queue offloads API") trying

ethdev: add port ownership
The ownership of a port is implicit in DPDK.
Making it explicit is better from the next reasons:
1. It will define well who is in charge of the port usage synchronization.
2. A library could work on top of a port.
3. A port can work on top of another port.
Also in the fail-safe case, an issue has been met in testpmd.
We need to check that the application is not trying to use a port which
is already managed by fail-safe.
A port owner is built from owner id(number) and owner name(string) while
the owner id must be unique to distinguish between two identical entity
instances and the owner name can be any name.
The name helps to logically recognize the owner by different DPDK
entities and allows easy debug.
Each DPDK entity can allocate an owner unique identifier and can use it
and its preferred name to owns valid ethdev ports.
Each DPDK entity can get any port owner status to decide if it can
manage the port or not.
The mechanism is synchronized for both the primary process threads and
the secondary processes threads to allow secondary process entity to be
a port owner.
Add a synchronized ownership mechanism to DPDK Ethernet devices to
avoid multiple management of a device by different DPDK entities.
