[PULL 7/9] pc-bios/s390-ccw/netmain: Fix error messages with regards to the TFTP server

[Thomas Huth <thuth@redhat.com>]

The code in net_init_ip() currently bails out early if "rc" is less
than 0, so the if-statements that check for negative "rc" codes to
print out some specific error messages with regards to the TFTP server
are never reached. Move them earlier to bring that dead code back to
life.
