s390/mm: correct return value of pmd_pfn
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. Cc: stable@vger.kernel.org # 3.17+ Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
