Eric Farman 4eb919663d vfio/ccw: Check return code from subchannel quiesce
If a subchannel is busy when a close is performed, the subchannel
needs to be quiesced and left nice and tidy, so nothing unexpected
(like a solicited interrupt) shows up while in the closed state.
Unfortunately, the return code from this call isn't checked,
so any busy subchannel is treated as a failing one.

Fix that, so that the close on a busy subchannel happens normally.
