_have_xfs() does return true/false and can be used with && or in a

Per [1], my opinion is that using && in the requires() function where
the return value is ignored is confusing so I prefer not to do it in new
code.

If we want to reconsider this we, should add a check to ensure the
return value of requires() matches the expectation of the global
variable it uses.
