LU-1118 llite: Invoke file_update_time in page_mkwrite

Upstream commit 41c4d25f78c01ede13efee1f2e979f3f35dd26f6
Only update file times if page_mkwrite is not set. So we
need call file_update_time by ourselves. Since all we
supported kernel have included this change. Then config
check is unnecessary.
