[PATCH net-next v3] geneve: Initialize addr6 with memset

[Nathan Chancellor]

Clang warns:

drivers/net/geneve.c:428:29: error: suggest braces around initialization
of subobject [-Werror,-Wmissing-braces]
                struct in6_addr addr6 = { 0 };
                                          ^
                                          {}

Rather than trying to appease the various compilers that support the
kernel, use memset, which is unambiguous.

Fixes: a07966447f39 ("geneve: ICMP error lookup handler")

v1 -> v2:

* Just remove the zero instead of adding more braces as it seems to
  match the rest of the kernel (as suggested by Joe Perches).

v2 -> v3:

* Use memset as suggested by David Miller.
