[9fans] Patch to stop a debug message in 9/pc/sdata.c

[Richard Powell <richard@powell.name>]

Greetings,

Here is a patch for /sys/src/9/pc/sdata.c to eliminate an anoying "IBsy+" message that appears when I use two ATA drives 
at once.  I have one drive on each port of a HPT-370 ATA-100 chip.  I think the message is a result of the fact that the 
chip only uses one IRQ.

Thanks,
Richard
