zfcp: cleanup and add statistics

James

please drop my first attempt for the zfcp add statistics patch and instead use the 2 which are following.

Patch 1: whitespace cleanup.
Patch 2: the modified zfcp add statistics patch

This patchset was created due to the comments from Heiko Carstens pointing out a few things which could be improved.

Sorry, for the inconvenience.

Cheers Swen.
