RDMA/mlx5: Fix existence check for extended address vector

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")
