[dpdk-dev] [PATCH v4 06/11] net/mlx5: remove handling of ICMP fragmented packets

Commit [1] forced setting of match on 'frag' bit mask 1 and value 0.
Previous patch in this series added support of match on fragmented and
non-fragmented packets on L3 items, so this setting is now redundant.

This patch removes the changes done in [1].

[1] commit 85407db9f60d ("net/mlx5: fix matching for ICMP fragments")
