log: count_codecs(): drop logging of non-TCH lchan types

count_codecs() is called on every chan act ack, also for channels other than
TCH/F and TCH/H. So this logging happens a lot during normal operation but adds
no real information.

Also, RSL would be the wrong logging category for this -- RSL is about the RSL
communications, not whether our internal code tries to count lchan codecs for
the wrong channel types.
