iotests: Test active commit with iothread and background I/O
This is a better regression test for the bugs hidden by commit 80fc5d26
('graph-lock: Disable locking for now'). With that commit reverted, it
hangs instantaneously and reliably for me.
It is important to have a reliable test like this, because the following
commits will set out to fix the actual root cause of the deadlocks and
then finally revert commit 80fc5d26, which was only a stopgap solution.

graph-lock: Unlock the AioContext while polling
If the caller keeps the AioContext lock for a block node in an iothread,
polling in bdrv_graph_wrlock() deadlocks if the condition isn't
fulfilled immediately.
Now that all callers make sure to actually have the AioContext locked
when they call bdrv_replace_child_noperm() like they should, we can
change bdrv_graph_wrlock() to take a BlockDriverState whose AioContext
lock the caller holds (NULL if it doesn't) and unlock it temporarily
while polling.

file-posix: remove incorrect coroutine_fn calls
raw_co_getlength is called by handle_aiocb_write_zeroes, which is not a
coroutine
function. This is harmless because raw_co_getlength does not actually suspend,
but in the interest of clarity make it a non-coroutine_fn that is just wrapped
by the coroutine_fn raw_co_getlength. Likewise, check_cache_dropped was only
a coroutine_fn because it called raw_co_getlength, so it can be made
non-coroutine
as well.
