checksum: Make csum_ip4_header() take a host endian length

csum_ip4_header() takes the packet length as a network endian value.  In
general it's very error-prone to pass non-native-endian values as a raw
integer.  It's particularly bad here because this differs from other
checksum functions (e.g. proto_ipv4_header_psum()) which take host native
lengths.

It turns out all the callers have easy access to the native endian value,
so switch it to use host order like everything else.
