nodemask: propagate boolean for nodes_and{,not}

Patch series "nodemask: align nodes_and{,not} with underlying bitmap ops".

nodes_and{,not} are void despite that underlying bitmap_and(,not) return
boolean, true if the result bitmap is non-empty.  Align nodemask API, and
simplify client code.


This patch (of 3):

Bitmap functions bitmap_and{,not} return boolean depending on emptiness of
the result bitmap.  The corresponding nodemask helpers ignore the returned
value.

Propagate the underlying bitmaps result to nodemasks users, as it
simplifies user code.
