mlx5: Remove uninitialized use of key in mlx5_core_create_mkey

Clang warns:

               = '\0'
1 warning generated.

key's initialization was removed in commit fc6a9f86 ("{IB,net}/mlx5:
Assign mkey variant in mlx5_ib only") but its use was not fully removed.
Remove it now so that there is no more warning.

Fixes: fc6a9f86 ("{IB,net}/mlx5: Assign mkey variant in mlx5_ib only")
