net/mlx5: fix Rx queue flags on destroying flow

After inserting an offload flow, the software flag information will
be updated based on the flow. When receiving a packet on this queue,
the hardware packet type bits and the software flag will be used
together to get the inner packet and tunnel header type (if any) from
the global packet type table.
When destroying a flow, the corresponding Rx queue flag needs to be
updated. All flags should be cleared when closing a device because
all control flows and application flows are invalid anymore.
Such behavior is missed when implementing the non-cached mode.

examples/ipsec-gw: fix gcc 10 maybe-uninitialized warning

gcc 10.0.1 reports:

../examples/ipsec-secgw/ipsec_process.c: In function ‘ipsec_process’:
../examples/ipsec-secgw/ipsec_process.c:132:34:

  132 |    grp[n].cnt = pkts + i - grp[n].m;
      |                            ~~~~~~^~

This is a correct warning for the initial execution of the statement.
However, it is the design of the loop that grp[0].cnt will later be
written with the correct value using an initialized grp[0].m before it
is used.

In order to remove the warning, initialize grp[0].m for the initial and
unused calculation of grp[0].cnt.

examples/l3fwd-power: exit on power lib init failure

Currently, if power library initialization fails, only a log message is
displayed. This is suboptimal for a number of reasons, but the main one
is that telemetry mode does not depend on the power library and can
therefore run in environments where l3fwd-power would normally not run
correctly (such as inside a VM). This will lead to attempts to
deinitialize the power library on exit, with a subsequent forced unclean
shutdown of DPDK.

Fix this by only initializing the power library in modes that actually
need it, and change a log message to a failure to initialize.
