Don't let bugs in ide_pci.c break wdprobe(), at least for standard

Browse Source 
IDE hardare.  The attempted fix in rev.1.182 was a no-op except for
adding dozens of style bugs.  The undocumented options ALI_V and
DISABLE_PCI_IDE go away as a side effect.  ALI_V was a no-op because
rev.1.182 was a no-op.  DISABLE_PCI_IDE didn't actually disable
PCI IDE.  It disabled the buggy code in wdprobe() at a cost of
completely breaking support for Promise controllers.

Broken in:	rev.1.139
