[PATCH v5 0/4] blockdev: avoid acquiring AioContext lock twice at do_drive_backup and do_blockdev_backup

do_drive_backup() acquires the AioContext lock of the corresponding BlockDriverState. This is not a problem when it's called from qmp_drive_backup(), but drive_backup_prepare() also acquires the lock before calling it. The same things happens with do_blockdev_backup() and blockdev_backup_prepare().
