blockdev: no need to drain in qmp_block_commit
Draining is not necessary, I/O can happen as soon as the
commit coroutine yields. Draining can be necessary before
reopening the file for read/write, or while modifying the
backing file chain, but that is done separately in
bdrv_reopen_multiple or bdrv_close; this particular
bdrv_drain_all does nothing for that.
