Current default queue pairs number when creating a VF is 16. In order to support up to 256 queue pairs, enable this request queues function. Since request queues command may return event message, modify function iavf_read_msg_from_pf to identify event opcode and mark VF reset status.

Use new virtchnl opcodes and structures to help indicate up to 256 queue pairs. Need to request additional queues from PF first if the current allocated queues are not enough.
