net/mlx5e: CT, Fix coverity issue
The cited commit introduced the following coverity issue at function
mlx5_tc_ct_rule_to_tuple_nat:
- Memory - corruptions (OVERRUN)
Overrunning array "tuple->ip.src_v6.in6_u.u6_addr32" of 4 4-byte
elements at element index 7 (byte offset 31) using index
"ip6_offset" (which evaluates to 7).
In case of IPv6 destination address rewrite, ip6_offset values are
between 4 to 7, which will cause memory overrun of array
"tuple->ip.src_v6.in6_u.u6_addr32" to array
"tuple->ip.dst_v6.in6_u.u6_addr32".
Fixed by writing the value directly to array
"tuple->ip.dst_v6.in6_u.u6_addr32" in case ip6_offset values are
between 4 to 7.
