enic: set skb->hash type properly
Driver sets the skb l4/l3 hash based on NIC_CFG_RSS_HASH_TYPE_*,
which is bit mask. This is wrong. Hw actually provides us enum.
Use CQ_ENET_RQ_DESC_RSS_TYPE_* to set l3 and l4 hash type.
Fixes: bf751ba802fe ("driver/net: enic: record q_number and rss_hash for skb")
