	wd.c 
Log Message:
Various:
Put WDF_ERROR in the wdc_softc, to avoid gratuitously forcing non-active drives
into single-sector mode on the next transfer.  Arrange to wait for an interrupt
after wdsetctlr(); this avoids long busy-wait delays, and gets rid of the
`extra interrupt' messages (except for one immediately after autoconfig on some
machines).  Replace some uses of wdsetctlr() with simply lowering wd->sc_state;
no point in forcing this immediately.  Allow control operations to time out.
Enable the warnings for long busy-wait delays by default.  Some other minor
things not worth mentioning.
