[PATCH iproute2-next] "ip help" wrong output, exit code.

[Dmitri Seletski <drjoms@gmail.com>]

Changed output of "ip help" from standard error to standard output. And 
Exit is now 0 instead of -1. "ip help|grep bridge" - now gives bridge 
syntax instead of flooding user with everything from "ip help".
