In wdcprobe1(), protect the register writability test with splbio().
What we do here seems to trigger interrupts on some pcmcia adapters, which
cause the kernel to hang.
Add some WDCDEBUG_PRINT((), DEBUG_PROBE).
Avoid touching registers of nonexistent drives, once we know which drive is
or is not here.
This makes the "IBM PCMCIA Portable CD-ROM Drive" (external CD drive with
PCMCIA adapter) work.
