Why don't use ice_dcf_send_cmd_req_no_irq? all the other virtual channel interface are called by ice_dcf_send_cmd_req_no_irq in dcf, like ice_dcf_get_vf_vsi_map

ice_dcf_send_cmd_req_no_irq() are always used combined with ice_dcf_recv_cmd_rsp_no_irq(), their function is the same as ice_dcf_execute_virtchnl_cmd().
The difference is that ice_dcf_send_cmd_req_no_irq() is used in initialization, before the interrupt is enabled. ice_dcf_execute_virtchnl_cmd() should be used after interrupt enable for safety.

In this way, I think it is better to use ice_dcf_execute_virtchnl_cmd() here since these functions will be called after initialization.

Best Regards,
Xu, Ting
