OK, now done as 24/23. Apparently we can now get rid of the code dealing
with drive==-1 in lock_fdc()/set_fdc() etc. It's only used by
user_reset_fdc() and the last call place is in floppy_resume() which
even forgets to set the fdc number, so it only resets the current FDC,
as many times as there are FDCs in the system. I'm going to fix this
one and see make sure we drop this special case of -1.
