struct kiocb has a 2 bytes hole that developed post commit 41d36a9f3e53

But write hint has made a comeback with commit 449813515d3e ("block, fs:
Restore the per-bio/request data lifetime fields").
This patch uses the leftover space in kiocb to carve 1 byte field
ki_write_hint.
Restore the code that operates on kiocb to use ki_write_hint instead of
inode hint value.
This does not bring any behavior change, but needed to enable per-io
hints (by another patch).
