s390/mm: Fix DirectMap accounting
With uncoupling of physical and virtual address spaces population of
the identity mapping was changed to use the type POPULATE_IDENTITY
instead of POPULATE_DIRECT. This breaks DirectMap accounting:
> cat /proc/meminfo
DirectMap4k: 55296 kB
DirectMap1M: 18446744073709496320 kB
Adjust all locations of update_page_count() in vmem.c to use
POPULATE_IDENTITY instead of POPULATE_DIRECT as well. With this
accounting is correct again:
> cat /proc/meminfo
DirectMap4k: 54264 kB
DirectMap1M: 8334336 kB
