shmem: set shmem_writepage() variables early
shmem_writepage() sets up variables typically used *after* a possible huge
page split. However even if that does happen the address space mapping
should not change, and the inode does not change either. So it should be
safe to set that from the very beginning.
This commit makes no functional changes.
