ipv6: tcp: enable flowlabel reflection in some RST packets
When RST packets are sent because no socket could be found,
it makes sense to use flowlabel_reflect sysctl to decide
if a reflection of the flowlabel is requested.
This extends commit 22b6722bfa59 ("ipv6: Add sysctl for per
namespace flow label reflection"), for some TCP RST packets.
In order to provide full control of this new feature,
flowlabel_reflect becomes a bitmask.
