net/mlx5e: Again mutually exclude RX-FCS and RX-port-timestamp

Browse Source 
[ Upstream commit da6192ca72d5ad913d109d43dc896290ad05d98f ]

Commit 1e66220948df8 ("net/mlx5e: Update rx ring hw mtu upon each rx-fcs
flag change") seems to have accidentally inverted the logic added in
commit 0bc73ad46a ("net/mlx5e: Mutually exclude RX-FCS and
RX-port-timestamp").

The impact of this is a little unclear since it seems the FCS scattered
with RX-FCS is (usually?) correct regardless.

Fixes: 1e66220948df8 ("net/mlx5e: Update rx ring hw mtu upon each rx-fcs flag change")
