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_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
