ipv6: enable IPV6_FLOWLABEL_MGR for getsockopt
It is already possible to set/put/renew a label
with IPV6_FLOWLABEL_MGR and setsockopt. This patch
add the possibility to get information about this
label (current value, time before expiration, etc).
It helps application to take decision for a renew
or a release of the label.
v2:
* Add spin_lock to prevent race condition
* return -ENOENT if no result found
* check if flr_action is GET
v3:
* move the spin_lock to protect only the
relevant code
