Subject: [PATCH iwl-next v6 2/6] igb: Remove static qualifiers

From: Sriram Yagnaraman <sriram.yagnaraman@....tech>

Remove static qualifiers on the following functions to be able to call
from XSK specific file that is added in the later patches:
- igb_xdp_tx_queue_mapping()
- igb_xdp_ring_update_tail()
- igb_clean_tx_ring()
- igb_clean_rx_ring()
- igb_xdp_xmit_back()
- igb_process_skb_fields()
