PCI: cleanup MSI code
Cleanup MSI code as follows: - fix some types - fix strange local variable definition - delete unnecessary blank line - add comment to #endif which is far from corresponding #ifdef Signed-off-by: Satoru Takeuchi <takeuchi_satoru@jp.fujitsu.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
