mpt2sas_scsih_event_callback - firmware event handler (called at ISR time) : per adapter object : MSIX table index supplied by the OS : reply message frame(lower 32bit addr) Context: interrupt.
This function merely adds a new work task into ioc->firmware_event_thread. The tasks are worked from _firmware_event_work in user context.
Return 1 meaning mf should be freed from _base_interrupt 0 means the mf is freed from this function.
