Fix a typo that causes 'low resources' to erroneously kick in

This patch fixes a typo which caused XENNET to operate in a 'low resources'
situation most of the time. This was almost certainly causing performance
issues and, oddly, caused the NDISTest 6.5 OffloadChecksum test to fail...
but only on Windows 8.0.
