lttng-modules-dkms failed to build with 4.14 Azure edge kernel on

Bug description:
SRU request, Xenial, Artful
[Impact]
lttng dkms modules fail to build against newer HWE kernels because of
missing 4.14 compat fixes that allow it to build against newer 4.14
kernels.
[Fix]
Upstream lttng 4.14 compat fixes.
[Testcase]
Without the fix, running the kernel team autotest lttng regression test suite
fails because the module does not build and install. With the fix the lttng
smoke tests pass.
To run the test:
sudo autotest/client/autotest-local
autotest/client/tests/ubuntu_lttng_smoke_test/control
using git://kernel.ubuntu.com/ubuntu/autotest and
git://kernel.ubuntu.com/ubuntu/autotest-client-tests
[Regression Potential]
lttng fails to build and work against older kernels. As the new code is
#if'def'd compat code the 4.14 specific changes are not built into the older
kernels, so this risk is small.
