net/mlx5: DR, Don't allow match on IP w/o matching on full ethertype/ip_version

net/mlx5: DR, Don't allow match on IP w/o matching on full ethertype/ip_version

commit ffb0753b954763d94f52c901adfe58ed0d4005e6 upstream.

Currently SMFS allows adding rule with matching on src/dst IP w/o matching
on full ethertype or ip_version, which is not supported by HW.
This patch fixes this issue and adds the check as it is done in DMFS.
