mm: shmem: add mTHP size alignment in shmem_get_unmapped_area
Although the top-level hugepage allocation can be turned off, anonymous
shmem can still use mTHP by configuring the sysfs interface located at
'/sys/kernel/mm/transparent_hugepage/hugepage-XXkb/shmem_enabled'.
Therefore, add alignment for mTHP size to provide a suitable alignment
address in shmem_get_unmapped_area().
