[PATCH] net/ixgbe: fix IPv6 mask in fdir

[Kaiwen Deng]

Rules without addr mask cannot be created together in ixgbe
when setting IPv6 addr mask to default value as 0.

This commit is to change the default value of IPv6 addr mask as '0xFF'.

Fixes: cba954b7beda ("net/ixgbe: enable IPv6 mask in flow rules")
Fixes: 7d629cacedee ("net/ixgbe: enable IPv6 for consistent API")
