Merge branch 'selftests-drv-net-stats-use-skip-instead-of-xfail'

====================
selftests: drv-net: stats: use skip instead of xfail

Alex posted support for configuring pause frames in fbnic. This flipped
the pause stats test from xfail to fail. Because CI considered xfail as
pass it now flags the test as failing. This shouldn't happen. Also we
currently report pause and FEC tests as passing on virtio which doesn't
make sense.
