All three of these drivers abused cv_waitq_empty in the same way by spinning 

on it in hopes of making sure that the waitq was empty before going on.
This wasn't needed and probably never would have worked as intended.  Now
that cv_waitq_empty() and friends are gone, the code in these drivers that
spins on it can go away too.  This should unbreak LINT.
