[RFC][PATCH][5/8] PCI PM: Consistently use variable name "error" for pm call return values

["Rafael J. Wysocki" <rjw@sisk.pl>]

From: Frans Pop <elendil@planet.nl>

I noticed two functions use a variable "i" to store the return value of PM
function calls while the rest of the file uses "error". As "i" normally
indicates a counter of some sort it seems better to keep this consistent.
