In case of a Secure-Storage-Access exception the effective aka virtual
address which caused the exception is contained within the TEID.
do_secure_storage_access() incorrectly uses phys_to_folio() instead of
virt_to_folio() to translate the virtual address to the corresponding
folio.
Fix this by using virt_to_folio() instead of phys_to_folio().
