loopback: Drop obsolete ip_summed setting
Now that the network stack can handle inbound packets with partial
checksums, we should no longer clobber the ip_summed field in the
loopback driver. This is because CHECKSUM_UNNECESSARY implies that
the checksum field is actually valid which is not true for loopback
packets since it's only partial (and thus complemented).
This allows packets from lo to then be SNATed to an external source
while still preserving the checksum's validity.
