Subject: [PATCH net 1/4] i40e: Fix error handling in i40e_vsi_open

From: Dinghao Liu <dinghao.liu@....edu.cn>

When vsi->type == I40E_VSI_FDIR, we have caught the return value of
i40e_vsi_request_irq() but without further handling. Check and execute
memory clean on failure just like the other i40e_vsi_request_irq().

Fixes: 8a9eb7d3cbcab ("i40e: rework fdir setup and teardown")
