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).
