Subject: i40e: Fix incorrect address type for IPv6 flow rules
Patch-mainline: v6.0-rc3
Git-commit: bcf3a156429306070afbfda5544f2b492d25e75b
References: jsc#SLE-18378

It was not possible to create 1-tuple flow director
rule for IPv6 flow type. It was caused by incorrectly
checking for source IP address when validating user provided
destination IP address.

Fix this by changing ip6src to correct ip6dst address
in destination IP address validation for IPv6 flow type.

Fixes: efca91e89b67 ("i40e: Add flow director support for IPv6")
