Subject: [PATCH net] net/mlx4e: Remove redundant definition of IB_MTU_XXX

From: Mark Zhang <markzhang@...dia.com>

Remove them to avoid "redeclaration of enumerator" build error, as they
are already defined in ib_verbs.h. This is needed for the following
patch, which need to include the ib_verbs.h.

Fixes: 096335b3f983 ("mlx4_core: Allow dynamic MTU configuration for IB ports")
