Subject: RDMA/mlx5: Fix existence check for extended address vector
Patch-mainline: v4.13-rc5
Git-commit: 931b3c1a832621b4bdcbaf783096fc267eb36fbe
References: bsc#1046305 FATE#322943

The extended address vector is the highest bit in be32 variable,
but it was compared with the lowest. This patch fixes the endianness
of that check and removes already declared define.

Fixes: 17d2f88f92ce ("IB/mlx5: Add ODP atomics support")
