Flow director rules matching traffic properties above layer 2 do not
target a fixed hash Rx queue (HASH_RXQ_ETH), it actually depends on the
highest protocol layer specified by each flow rule.
mlx5_fdir_filter_delete() makes this wrong assumption and causes a crash
when attempting to destroy flow rules with L3/L4 specifications.
