[PATCH 1/12] iseries_veth: Make error messages more user friendly, and add a debug macro

[Michael Ellerman]

Currently the iseries_veth driver prints the file name and line number in its
error messages. This isn't very useful for most users, so just print
"iseries_veth: message" instead.

Also add a veth_debug() and veth_info() macro to replace the current
veth_printk().
