Conrad Meyer c114e74120 ioat(4): Allow callouts to be scheduled after hw reset ...

is_completion_pending governs whether or not a callout will be scheduled
when new work is queued on the IOAT device.  If true, a callout is
already scheduled, so we do not need a new one.  If false, we schedule
one and set it true.  Because resetting the hardware completed all
outstanding work but failed to clear is_completion_pending, no new
callout could be scheduled after a reset with pending work.

This resulted in a driver hang for polled-only work.
