IB/mlx4: Fix an error handling path in 'mlx4_ib_rereg_user_mr()'

[ Upstream commit 3dc7c7badb7502ec3e3aa817a8bdd9e53aa54c52 ]

Before returning -EPERM we should release some resources, as already done
in the other error handling path of the function.

Fixes: d8f9cc328c88 ("IB/mlx4: Mark user MR as writable if actual virtual memory is writable")
