net/mlx5e: IPsec: Fix Software parser inner l3 type setting in case of encapsulation
Current code wrongly uses the skb->protocol field which reflects the
outer l3 protocol to set the inner l3 type in Software Parser (SWP)
fields settings in the ethernet segment (eseg) in flows where inner
l3 exists like in Vxlan over ESP flow, the above method wrongly use
the outer protocol type instead of the inner one. thus breaking cases
where inner and outer headers have different protocols.
Fix by setting the inner l3 type in SWP according to the inner l3 ip
header version.
