exthdr: remove unused variable uval8

Was added but not used in d7b451fe1a45 (src: add TCP option matching
requirements, 2017-02-07). Fixes the following warning:

expr/exthdr.c: In function ‘nftnl_expr_exthdr_json_parse’:
expr/exthdr.c:244:10: warning: unused variable ‘uval8’ [-Wunused-variable]
  uint8_t uval8;
          ^~~~~
