This removes two inlines which were both called in a single function only:
1) dccp_feat_change() is always called with either DCCPO_CHANGE_L or DCCPO_CHANGE_R as argument
* from dccp_set_socktopt_change() via do_dccp_setsockopt() with DCCP_SOCKOPT_CHANGE_R/L
* from __dccp_feat_init() via dccp_feat_init() also with DCCP_SOCKOPT_CHANGE_R/L.
Hence the dccp_feat_is_valid_type() is completely unnecessary and always returns true.
2) Due to (1), the length test reduces to 'len >= 4', which in turn makes
dccp_feat_is_valid_length() unnecessary.
Furthermore, the inline function dccp_feat_is_reserved() was unfolded,
since only called in a single place.
