From: Xiao Yang <yangx.jy@xxxxxxxxxxx>
rxe_mr_init_user() always returns the fixed -EINVAL when ib_umem_get()
fails so it's hard for user to know which actual error happens in
ib_umem_get(). For example, ib_umem_get() will return -EOPNOTSUPP
when trying to pin pages on a DAX file.
Return actual error as mlx4/mlx5 does.
