b43legacy: fix led naming

Fixed led device naming for the b43legacy driver. Due to the
documentation of the led subsystem/class the naming should be
"devicename:colour:function" while not applying sections
should be left blank.

This should lead to e.g. "b43legacy-%s::rx" instead of
"b43legacy-%s:rx".
