[PATCH 1/2] pci: cleanup whitespace

[Stephen Hemminger <stephen-OTpzqLSitTUnbdJkjeBofR2eb7JE58TQ@public.gmane.org>]

Fix whitespace errors reported by checkpatch, including
missing space around operators and places where tab should
be used instead of space.

Signed-off-by: Stephen Hemminger <stephen-OTpzqLSitTUnbdJkjeBofR2eb7JE58TQ@public.gmane.org>
