[PATCH net-next 1/4 v2] net: sh_eth: remove unnecessary function

[PATCH net-next 1/4 v2] net: sh_eth: remove unnecessary function

[Shimoda, Yoshihiro]

The sh_eth_timer() called mod_timer() for itself. So, this patch
removes the function.

 about v2:
  - rebase the latest net-next.git
  - I don't submit the NAPI patch this time
