s390/mm: fix direct map accounting
Commit bb1520d581a3 ("s390/mm: start kernel with DAT enabled") did not
implement direct map accounting in the early page table setup code. In
result the reported values are bogus now:
$cat /proc/meminfo
...
DirectMap4k: 5120 kB
DirectMap1M: 18446744073709546496 kB
DirectMap2G: 0 kB
Fix this by adding the missing accounting. The result looks sane again:
$cat /proc/meminfo
...
DirectMap4k: 6156 kB
DirectMap1M: 2091008 kB
DirectMap2G: 6291456 kB
Fixes: bb1520d581a3 ("s390/mm: start kernel with DAT enabled")
