dont count requeued io as outstanding io. there is a 1:1 mapping
between calls to bufq_enqueue and bufq_done calls, but bufq_requeue
can be called multiple times on an io in between the enqueue and
done. if you keep incrementing outstanding you'll never stop sleeping
for suspend.
bufq_requeue can be called via interrupts, so we cannot sleep
there.
the problems fixed by this diff were never hit cos the adapters
people are testing/running with do not cause bufq_requeue to be
called.
thanks to thib@ for helping me understand the code better
