mm: fix shmem THP counters on migration
The per node numa_stat values for shmem don't change on page migration for
THP:
grep shmem /sys/fs/cgroup/machine.slice/.../memory.numa_stat:
shmem N0=1092616192 N1=10485760
shmem_thp N0=1092616192 N1=10485760
migratepages 9181 0 1:
shmem N0=0 N1=1103101952
shmem_thp N0=1092616192 N1=10485760
Fix that by updating shmem_thp counters likewise to shmem counters on page
migration.
