Wayne Boyer 64ffdb7622 [SCSI] ipr: improve interrupt service routine performance 
During performance testing on P7 machines it was observed that the interrupt
service routine was doing unnecessary MMIO operations.

This patch rearranges the logic of the routine and moves some of the code out
of the main routine.  The result is that there are now fewer MMIO operations in
the performance path of the code.
