Subject: [PATCH 01/17] vfio/pci: Use unsigned int instead of unsigned

checkpatch.pl warns about usage of bare unsigned.

Change unsigned to unsigned int to eliminate checkpatch.pl
warnings about existing code that are encountered by changes to the
interrupt management code at or near lines using bare unsigned.
