s390/mm: Add __context_unsafe() attribute to do_secure_storage_access()

Browse source

Compiling do_secure_storage_access() with context analysis enabled
results in this warning:

arch/s390/mm/fault.c:472:3: warning: releasing spinlock 'fw.ptl' that was not held
  472 |                 folio_walk_end(&fw, vma);

Problem is that folio_walk_end() comes without the required context
analysis attribute. Also the proper attribute cannot be added easily,
since folio_walk_end() is a macro, and not a function.

For the time being disable context analysis only for
do_secure_storage_access() until this is resolved.
