s390/mm: Use handle_fault_error() in do_secure_storage_access()

Browse source

Similar to the normal exception handler use handle_fault_error() which
handles accesses from user space and kernel space differently.

This also addresses failing kernel accesses via e.g. copy_from_user() to
user space: instead of an endless loop, the fixup handling is performed.
Even though this could only happen if arch_make_folio_accessible() would
permanently fail, which is not realistic.

Therefore this is rather a cleanup patch.
