o Remove unnecessary sanity check involving requested offset of extended   attribute read--the offset is required to be 0 by an earlier check,   meaning that it will always be within the scope of the attribute data.   This change should have no impact on executed code paths other than   removing the unnecessary check: please report if any new failures   start to occur as a result.
