Bug 7785: (follow-up) standardize POD

This makes the POD for the columns() function consistent
with the rest of C4/Members.pm.  It also removes a note
that can be relegated to the bug report and the Git
history.

Also, since C4::Members::columns() is not actually a
class method, this patch changes the invocation to
not call it that way.
