block: Cancel jobs first in bdrv_close_all()
So far, bdrv_close_all() first removed all root BlockDriverStates of BlockBackends and monitor owned BDSes, and then assumed that the remaining BDSes must be related to jobs and cancelled these jobs. This order doesn't work that well any more when block jobs use BlockBackends internally because then they will lose their BDS before being cancelled. This patch changes bdrv_close_all() to first cancel all jobs and then remove all root BDSes from the remaining BBs.
