ext/lame/gstlame.c: Fix up bitrate checking macro. Make it give us a

Browse source 
Original commit message from CVS:
* ext/lame/gstlame.c: (gst_lame_sink_setcaps),
(gst_lame_set_property), (gst_lame_setup):
Fix up bitrate checking macro.  Make it give us a
GST_ELEMENT_WARNING message so the application has a chance of
reporting this to the user.  Move the checking to _setup, so we
are sure it runs in the READY state, when we hope to have a pipeline
and a bus that is not flushing.
This fixes e.g. using 96 kbit/sec as a bitrate.
