ALSA: hda/intel: Make sure to cancel irq-pending work at closing PCM stream
The pending irq work might be still floating while the assigned stream
has been already closed, which may lead to UAF, especially when
another async work for fasync is involved.
For addressing this, extend the hda_controller_ops for allowing the
extra cleanup procedure that is specific to the controller driver, and
make sure to cancel and sync the pending irq work at each PCM close
before releasing the resources.
