Subject: i40iw: Move cqp_cmd_head init to CQP initialization
Patch-mainline: v4.15-rc1
Git-commit: d2782739c1498e4425dcdeb79f90f9291e58f6f6
References: bsc#1058659 FATE#322535

Control QP (CQP) command backlog list is initialized at
device initialization time.  It is not reinitialized in
the reset flow.  Move the initialization to CQP creation
time so the list can be initialized correctly for reset as well.

Fixes: 86dbcd0f12e9 ("i40iw: add file to handle cqp calls")
