net/i40e: announce request queue capability in PF

[ upstream commit 918e90b ]

A new feature requesting additional queues from PF is added in iavf;
before sending VIRTCHNL_OP_REQUEST_QUEUES op code, the offload
capability flag VIRTCHNL_VF_OFFLOAD_REQ_QUEUES will be checked.

And due to DPDK PF is still used by some cases, add this offload
capability flag in i40e PF.

Fixes: cbdbd36 ("net/i40e: support AVF basic interface")
