Misc. fixups:

- [1] Make the driver friendly towards kernel without PREEMPTION.
  Use msleep(9) instead of simple unlock-check_variable-lock mechanisme
  since the later not really effective in non-preemptible kernel
  (especially during codec detection routine).
- Free most driver resources in a sane manner to avoid possible
  double free and panics especially during device detach and codec
  detection failure.

MFC after:	3 days
