[SCSI] qla4xxx: Fix double clearing of risc_intr for ISP83XX 

Issue:
For ISP83XX risc_intr getting clear two times in case of polling mode.
risc_intr getting clear from interrupt_service_routine() as well
from process_mbox_intr() because of this driver may clear risc_intr
without processing interrupt.

Fix:
Do not clear risc_intr from process_mbox_intr().
