Florian Westphal 7509c7fdf9 fw_add_masquerade: remove unused function arguments
Similar to the previous commit.  All callers pass NULL.  This will
ease initial nftables backend implementation (less features to cover).

Add the function parameters as local variables and let compiler
remove branches.  Followup patch can remove the if (NULL) conditionals.
