mount/fuse: enable fuse real async dio when available
fuse has support for optimized async. direct I/O handling via the
FUSE_ASYNC_DIO init flag. Enable FUSE_ASYNC_DIO when advertised
by fuse.
performance/write-behind: fix dio hang
Also fix a hang observed during aio-stress testing due to conflicting
request handling in write-behind. Overlapping requests are skipped
in pick_winds and may never continue when the conflicting write in
progress returns. Add a wb_process_queue() call after a non-wb request
completes to keep the queue moving.
