introduce and use a flag indicating that interrupts are
enabled for this cbb. essentially this means that cbb
driver has completed it's initialization and is
ready to treat interrupts. this was exposed by
ccb's sharing their interrupt and pccbbintr() being called
for cbb which has not completed attachment due
to interrupt sharing.
