s390/mm: correct return value of pmd_pfn
[ Upstream commit 7cded342c09f633666e71ee1ce048f218a9c5836 ]
Git commit 152125b7a882df36a55a8eadbea6d0edf1461ee7
"s390/mm: implement dirty bits for large segment table entries"
broke the pmd_pfn function, it changed the return value from
'unsigned long' to 'int'. This breaks all machine configurations
with memory above the 8TB line.
