Log Message:
reintroduce ATACH_IRQ_WAIT flag for attachments using wdcintr(), only
process the interrupt when the flag is set - this fixes spurious interrupt
during post-reset drive setup in wdc_ata_bio_start(), and wdc_atapi_start()

while those functions set WDCTL_IDS, this seems to be ignored by certain
(maybe all) PCI-IDE controllers; usually the implicit KERNEL_LOCK() would
prevent the interrupt anyway, but not when the start routine is started
from the atabus thread, which doesn't take it

fixes 'panic: wdc_ata_bio_intr: bad state' reported on current-users
