Implement a common spkr_detach() function and call it from the
attachment-specific detach functions.  Returns EBUSY if the
device instance is busy, based on whether or not a sc->sc_inbuf
is allocated.  The buffer is malloc()d at spkropen time, and is
free()d in spkrclose().

Now we can actually implement the MODULE_CMD_FINI command and
unload the driver at will.
