[SRU Justification]
[Impact]
FTBFS against v5.3 kernels on Eoan/Focal.
[Fix]
* Backport fix from upstream commit f47729b94e11 (backport: rename ktime_get_boot_ns for v5.3+).
* Also updates -fcf-protection=none usage for bug
1830961.
[Test Case]
Verified DKMS module build on linux-oem/linux-oem-osp1/linux-generic >= 4.10 kernels on series Xenial/Bionic/Cosmic/Disco/Eoan and Focal.
[Regression Risk]
Low. There is no functional changes in comparison to 7906-0ubuntu1.
