[PATCH 4.2.y-ckt 58/59] cxgbi: fix uninitialized flowi6

[Kamal Mostafa]

4.2.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

From: Jiri Benc <jbenc@xxxxxxxxxx>

commit 3d6d30d60abb19ba9a20e53ce65b18a9c148fcd1 upstream.

ip6_route_output looks into different fields in the passed flowi6 structure,
yet cxgbi passes garbage in nearly all those fields. Zero the structure out
first.

Fixes: fc8d0590d9142 ("libcxgbi: Add ipv6 api to driver")
