lib: Fix SDP_TEXT_STR16/SDP_URL_STR16 parsing

sdp_extract_attr() uses the "size" parameter to return the number of
bytes consumed when parsing SDP Data Elements. This size is used to
advance a buffer pointer to parse next element.

This size was being incorrectly calculated for SDP_{TEXT,URL}_STR16 in
extract_str(), where the string length was added twice. The string
length is already added later in the function for {TEXT,URL}_STR{8,16}
by this statement:

*len += n;
