[dpdk-dev] [PATCH v3 1/3] net/failsafe: fix Rx safe check compiler hint

failsafe_rx_burst function is used when there are no sub-devices or at
least one of them has been removed, on the other hand, when all the
sub-devices are present, failsafe_rx_burst_fast function is used.

So it's really expected that some of the sub-devices will be unsafe for
Rx burst in failsafe_rx_burst execution.

Remove unlikely compiler hint from fs_rx_unsafe calling.
