iptopt: fix crash with invalid field/type combo
% nft describe ip option rr value
segmentation fault
after this fix, this exits with 'Error: unknown ip option type/field'.
Problem is that 'rr' doesn't have a value template, so the template struct is
all-zeroes, so we crash when trying to use tmpl->dtype (its NULL).
Furthermore, expr_describe tries to print expr->identifier but expr is
exthdr, not symbol: ->identifier contains garbage.
