[dpdk-dev] [PATCH] net/ice: fix sideband queue initialization

[dapengx.yu at intel.com]

From: Dapeng Yu <dapengx.yu at intel.com>

Sideband queue need to be initialized when device is initialized.
Otherwise the calling to function "ice_init_ctrlq" may fail.

This patch fixes it.

Fixes: 97f4f78bbd9f ("net/ice/base: add functions for device clock control")
