linkmode: Change return type of linkmode_andnot to bool

linkmode_andnot() simply returns the result of bitmap_andnot().
And the return type of bitmap_andnot() is bool.
So it makes sense for the return type of linkmode_andnot()
to also be bool.

I checked all call-sites and they either ignore the return
value or treat it as a bool.

Compile tested only.
