scsi: mpi3mr: Add support for threaded ISR
Register driver for threaded interrupts.
By default the driver will attempt I/O completion from interrupt context
(primary handler). Since the driver tracks per reply queue outstanding
I/Os, it will schedule threaded ISR if there are any outstanding I/Os
expected on that particular reply queue.
Threaded ISR (secondary handler) will loop for I/O completion as long as
there are outstanding I/Os (speculative method using same per reply queue
outstanding counter) or it has completed some X amount of commands
(something like budget).
