[RFC 00/11] make try_to_unmap simple

Currently, try_to_unmap returns various return value(SWAP_SUCCESS,
SWAP_FAIL, SWAP_AGAIN, SWAP_DIRTY and SWAP_MLOCK). When I look into
that, it's unncessary complicated so this patch aims for cleaning
it up. Change ttu to boolean function so we can remove SWAP_AGAIN,
SWAP_DIRTY, SWAP_MLOCK.

This patchset is based on v4.10-mmots-2017-02-28-17-33.
