Kevin Wolf a1a2af0756 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.
