extract_netinfo_args() should be a void function.

If there is no "netinfo" packet, extract_netinfo_args() will fail and cause
parse_device_path() to abort.  This basically meant that yaboot will fail to
load any kernel/initrd under those circumstances.

This fix changes extract_netinfo_args() to be a void function.
