- Fix the locking in dsp.c to prevent a LOR (AFAIK not on the LOR page).

- Remove an assertion in sound.c, it's not needed (and causes a panic now).
  From the conversation via mail between glebius and Ariff:

  Queue insertion/removal occur during
     1) driver loading (which is pretty much single thread /
        sequential) or unloading (mutex protected, bail out if there is
        any channel with refcount > 0 or busy).
     2) vchan_create()/destroy(), (which is *sigh* quite complicated), but
        somehow protected by 'master'/parent channel mutex. Other
        thread cannot add/remove vchan (or even continue traversing
        that queue) unless it can acquire parent channel mutex.
