[PATCH v4 7/8] s390/mm: Use goto statement in do_secure_storage_access()

[Heiko Carstens <hca@linux.ibm.com>]

Make do_secure_storage_access() look more like the do_exception()
by using a goto statement to get rid of an extra open coded
mmap_read_unlock() call.

Just cosmetic, no functional change.
