Merge branch 'renesas-dead-code'

Sergey Shtylyov says:

====================
Remove some dead code in the Renesas Ethernet drivers

Here are 2 patches against DaveM's 'net-next.git' repo. The Renesas drivers
call their ndo_stop() methods directly and they always return 0, making the
result checks pointless, hence remove them...
