nft: Use xtables_{m,c}alloc() everywhere
Make use of libxtables allocators where sensible to have implicit error checking. Leave library-internal calls in place to not create unexpected program exit points for users, apart from xt_xlate_alloc() as that function called xtables_error() in error case which exits by itself already.
