When the vhost-user-blk device lose the connection to the daemon during
the initialization phase it kills qemu because of the assert in the code.
The series fixes the bug.

0001 is preparation for the fix
0002 fixes the bug, patch description has the full motivation for the series
0003 (added in v3) fix bug on vm shutdown

Denis Plotnikov (3):
   vhost-user-blk: use different event handlers on initialization
   vhost-user-blk: perform immediate cleanup if disconnect on
   vhost-user-blk: add immediate cleanup on shutdown
