mm/mmap: replace SHM_HUGE_MASK with MAP_HUGE_MASK inside mmap_pgoff
Commit 091d0d55 ("shm: fix null pointer deref when userspace specifies invalid hugepage size") had replaced MAP_HUGE_MASK with SHM_HUGE_MASK. Though both of them contain the same numeric value of 0x3f, MAP_HUGE_MASK flag sounds more appropriate than the other one in the context. Hence change it back.
