Bug#883427: virtualbox-dkms: patch for 5.2.2-dfsg-2

[Carlo Valenti]

Package: virtualbox-dkms
Version: 5.2.2-dfsg-2

'r0drv/linux/timer-r0drv-linux.c' fails to build for kernel versions
>=~4.14.0 (git commit 185981d5), due to 'include/linux/timer.h'
recently dropping init_timer_pinned() in favor of newer timer_setup()

Patch:
