i40iw: Clear CQP Head/Tail during initialization

Browse source

Clear Control Queue Pair (CQP) Head/Tail on CQP
initialization as during an adapter reset, these
values are not reinitialized. Tail is cleared by
writing 0 to CQP's tail register. Head is cleared
by writing 0 to CQP's doorbell register.
