mgcp_client: cosmetic: clean up SDP params parsing
The mgcp_response_parse_params() is in a jumble. Straighten out these cosmetic
issues:
- Move assertion of r->body close to its first use.
- Instead of a talloc_zero and osmo_strlcpy dance, simply use talloc_strdup().
- Drop the first unused invocation of mgcp_find_section_end().
- Drop unused assignment of data_ptr = data.
- In the log, mention "SDP" to clarify.
- Add a comment clarifying how we skip the section marker.
