drm/msm: Add a way to override processes comm/cmdline
In the cause of using the GPU via virtgpu, the host side process is
really a sort of proxy, and not terribly interesting from the PoV of
crash/fault logging. Add a way to override these per process so that
we can see the guest process's name.
v2: Handle kmalloc failure, add comment to explain kstrdup returns
NULL if passed NULL [Dan Carpenter]
