Subject: RDMA/mlx5: Limit the scope of mlx5_ib_enable_driver function
Patch-mainline: v5.9-rc1
Git-commit: ac47bf5ef122591aa561fc16176ef0d1c7d24726
References: jsc#SLE-15175

The mlx5_ib_enable_driver() is local function and doesn't need to be
shared in mlx5_ib, so change it's signature to have static keyword in it.
