Xenial update to 4.4.65 stable release

[Stefan Bader]

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The 4.4.65 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://git.kernel.org/

    TEST CASE: TBD

The following patches from the 4.4.65 stable release shall be applied:
* tipc: make sure IPv6 header fits in skb headroom
* tipc: make dist queue pernet
* tipc: re-enable compensation for socket receive buffer double counting
* tipc: correct error in node fsm
* tty: nozomi: avoid a harmless gcc warning
* hostap: avoid uninitialized variable use in hfa384x_get_rid
* gfs2: avoid uninitialized variable warning
* tipc: fix random link resets while adding a second bearer
* tipc: fix socket timer deadlock
* xc2028: avoid use after free
* netfilter: nfnetlink: correctly validate length of batch messages
* tipc: check minimum bearer MTU
* vfio/pci: Fix integer overflows, bitmask check
* staging/android/ion : fix a race condition in the ion driver
* ping: implement proper locking
* perf/core: Fix concurrent sys_perf_event_open() vs. 'move_group' race
* Linux 4.4.65
