Fixes the following sparse warnings:
i40e_main.c:5953:32: warning: cast from restricted __le16
i40e_main.c:8008:29: warning: incorrect type in assignment (different base types)
i40e_main.c:8008:29: expected unsigned int [assigned] [usertype] ipa
i40e_main.c:8008:29: got restricted __le32 [usertype]
i40e_main.c:8008:29: warning: incorrect type in assignment (different base types)
i40e_main.c:8008:29: expected unsigned int [assigned] [usertype] ipa
i40e_main.c:8008:29: got restricted __le32 [usertype]
i40e_txrx.c:1950:59: warning: incorrect type in initializer (different base types)
i40e_txrx.c:1950:59: expected unsigned short [usertype] vlan_tag
i40e_txrx.c:1950:59: got restricted __le16 [usertype] l2tag1
i40e_txrx.c:1953:40: warning: cast to restricted __le16
i40e_xsk.c:448:38: warning: invalid assignment: |=
i40e_xsk.c:448:38: left side has type restricted __le64
i40e_xsk.c:448:38: right side has type int
Fixes: 2f4b411a3d67 ("i40e: Enable cloud filters via tc-flower")
Fixes: 2a508c64ad27 ("i40e: fix VLAN.TCI == 0 RX HW offload")
