Subject: [PATCH] scsi: pm8001: clean up structurally dead code when PM8001_USE_MSIX is defined (part2)

From: Colin Ian King <colin.king@...onical.com>

When macro PM8001_USE_MSIX is defined there is redundant dead code
call to pm8001_cr32.  Clean this up for the defined PM8001_USE_MSIX and
undefined PM8001_USE_MSIX cases.

Also rename the functions pm8001_chip_is_our_interupt,
pm80xx_chip_is_our_interupt and function pointer is_our_interrupt
to fix spelling mistakes.
