ice: virtchnl rss hena support
Add support for 2 virtchnl msgs:
VIRTCHNL_OP_SET_RSS_HENA
VIRTCHNL_OP_GET_RSS_HENA_CAPS
The first one allows VFs to clear all previously programmed
RSS configuration and customize it. The second one returns
the RSS HENA bits allowed by the hardware.
Introduce ice_err_to_virt_err which converts kernel
specific errors to virtchnl errors.
