payload: check icmp dependency before removing previous icmp expression

nft is too greedy when removing icmp dependencies.
'icmp code 1 type 2' did remove the type when printing.

Be more careful and check that the icmp type dependency of the
candidate expression (earlier icmp payload expression) has the same
type dependency as the new expression.
