  OVS team reports PMD compilation failed under: gcc (Ubuntu
13.2.0-4ubuntu3) 13.2.0

In function ‘mlx5dr_action_create_push_ipv6_route_ext_mhdr2’,
../drivers/net/mlx5/hws/mlx5dr_action.c:2701:64:
  ‘ipv6_dst_addr’ may be used uninitialized

Only shared action needs to query the IPv6 destination address
when creating dr_action. This is a false alert. Initialize it
to NULL to fix the warning.

Fixes: a50f6d3fe58d ("net/mlx5/hws: add IPv6 routing extension push remove actions")
