Well, for me it was even sufficient to restart just bacula-sd, this
unblocks the drive in turn.  I also think I found the root of all evil
that was eventually causing the hardware errors the changer reported
(which in turn made bacula-sd block the drive), it was probably a line
in the chio-bacula script my changer couldn't really stand.

Anyway, I'd still be interested in learning how to unblock the drive
/without/ cancelling the job, and restarting bacula-sd, i. e. a way to
tell bacula-sd: "Hey, all the trouble is gone, the hardware is fixed
again, please just continue now."
