[PATCH 5/7] net: Fix a misleading error message

[Markus Armbruster]

The error message

    $ qemu-system-x86_64 -netdev user,id=net0,ipv6-net=fec0::0/
    qemu-system-x86_64: -netdev user,id=net0,ipv6-net=fec0::0/: Parameter 
'ipv6-prefixlen' expects a number

points to ipv6-prefixlen instead of ipv6-net.  Fix:

    qemu-system-x86_64: -netdev user,id=net0,ipv6-net=fec0::0/: parameter 
'ipv6-net' expects a number after '/'
