Fix the fuzz failure in https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5574 :

The first time a value_string_ext() is accessed, _match_strval_ext_init() is
used before the real match function is called.  This function was not expanded
to take an idx parameter (in rev 35451).  It compiled only because the function:
  a) previously did not match _value_string_match_t
  b) and the difference was being cast away when assigning _match_strval to it
     (So the fact that the index parameter was not added was also ignored.)

To fix the problem, give _match_strval_ext_init() and index parameter and use
it instead of a dummy variable when calling the real match function.  That way
the first call to match_strval_ext_idx() will return an actual (initialized)
index.

To prevent the problem in the future, make the vse argument to
_match_strval_ext_init() const *and then cast away the constness* so the
function can modify the vse.
