[PATCH BUG-FIX] igbvf: fix the bug when initializing the igbvf

[Shan Wei <shanwei88@gmail.com>]

From: Samuel Liao <samuelliao@tencent.com>


Maybe it's a typo, but it cause that igbvf can't be initialized successfully.
Set perm_addr value using valid dev_addr, although which is equal to hw.mac.addr.
