blockdev: use drained_begin/end for qmp_block_resize
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1447551
If one tries to issue a block_resize while a guest is busy
accessing the disk, it is possible that qemu may deadlock
when invoking aio_poll from both the main loop and the iothread.
Replace another instance of bdrv_drain_all that doesn't
quite belong.
