tmpfs: fix highmem swapoff crash regression
Commit 778dd893ae78 ("tmpfs: fix race between umount and swapoff") forgot the new rules for strict atomic kmap nesting, causing WARNING: at arch/x86/mm/highmem_32.c:81 from __kunmap_atomic(), then BUG: unable to handle kernel paging request at fffb9000 from shmem_swp_set() when shmem_unuse_inode() is handling swapoff with highmem in use. My disgrace again.
