staging/brcm80211: fix minor checkpatch errors.

[Jason Cooper]

This is my first attempt at a large ( >4 lines ) patch, and my first use
of 'git send-email', please check thoroughly.  I've limited this patchset
to checkpatch.pl errors which were trivial to fix.

The next round of patches will fix the typedef warnings, and that should
take care of the remaining errors.  After that, I'll work on any remaining
warnings.

thx,

Jason.
