drm/msm/a6xx: Fix up QMP handling

Browse source

The commit referenced in the Fixes tag had a couple problems (as
pointed out by Dan):

- qmp_put was never called, resulting in refcnt leaks
- failling to acquire the QMP mailbox on A7xx would not undo the probe
  function properly
- the qmp_put call present in the code was unreachable

Fix all of these issues.
