xenoprof: drop unnecessary macro

This macro doesn't really provide a benefit. When support is added the
implementer can implement this how it needs to be and not conform to the
macro. Additionally this change limits the output of the warning to just
once instead of nrpages worth. While editing this area I dropped
trailing whitespace.
