Subject: [PATCH net-next 09/10] r8169:modify the behavior of function "rtl8168_oob_notify"

In function "rtl8168_oob_notify", change to using "rtl_eri_write" to
access eri 0xe8, instead of using "ERIDR" and "ERIAR" to access this reg.

For using function "rtl_eri_write" in function "rtl8168_oob_notify", move
down "rtl8168_oob_notify" related functions under function "rtl_eri_write".
