[Intel-wired-lan] [PATCH] igb: Fix error that repeat to add filter when changing adapter speed

[Gangfeng]

From: Gangfeng Huang <gangfeng.huang at ni.com>

Function igb_nfc_filter_exit()/igb_nfc_filter_restore() should be paried,
igb_nfc_filter_restore exist in igb_up(), but igb_nfc_filter_exit() exist
in __igb_close(), so move the igb_nfc_filter_exit() to igb_down().
