Subject: [PATCH v2] crypto: qat - Fix missing destroy_workqueue in adf_init_aer()

The adf_init_aer() won't destroy device_reset_wq when alloc_workqueue()
for device_sriov_wq failed. Add destroy_workqueue for device_reset_wq to
fix this issue.

Fixes: 4469f9b23468 ("crypto: qat - re-enable sriov after pf reset")
