i40e: check queue pairs num in config queues handler

Browse Source 
Check if num_queue_pairs number requested by VF is less than
maximum possible value in VIRTCHNL_OP_CONFIG_VSI_QUEUES handler.

Also check if local_vf_id >= 0 in common handler since it is of
int type and can potentially be negative.
