This fixes the problem that blockdev-create on a local file blocks the
main loop despite being a background job. This was caused by file-posix
preallocating the image with blocking syscalls rather than moving this
to the thread pool and yielding the coroutine meanwhile.
Kevin Wolf (2):
block: Convert .bdrv_truncate callback to coroutine_fn
file-posix: Make .bdrv_co_truncate asynchronous
