[PATCH] net: rtnetlink: use netif_oper_up instead of open code

The open code is defined as a new helper function(netif_oper_up) on netdev.h,
the code is dev->operstate == IF_OPER_UP || dev->operstate == IF_OPER_UNKNOWN.
Thus, replace the open code to netif_oper_up. This patch doesn't change logic.
