[PATCH 09/15] staging: brcm80211: fix off-by-one error in swap functions

[Arend van Spriel]

From: Henry Ptasinski <henryp at broadcom.com>

The original implementation iterated over the data in buf+1 through buf+size,
whereas it should have been over the data in buf through buf+size-1.

Tested on Mac G5 PPC and BCM63281.
