call bdrv_drain_all() even if the vm is stopped

There are still I/O operations when the vm is stopped. For example,
stop the vm, and do block migration. In this case, we don't drain all
I/O operation, and may meet the following problem:

qemu-system-x86_64: migration/block.c:731: block_save_complete: Assertion `block_mig_state.submitted == 0' failed.
