Michael S. Tsirkin 3d2d827f5c mm: move use_mm/unuse_mm from aio.c to mm/ ...

Anyone who wants to do copy to/from user from a kernel thread, needs
use_mm (like what fs/aio has).  Move that into mm/, to make reusing and
exporting easier down the line, and make aio use it.  Next intended user,
besides aio, will be vhost-net.
