[PATCH] drm/amdgpu/: Add missing kdoc entry in amdgpu_vm_handle_fault function

[Srinivasan Shanmugam]

This commit adds a description for the 'ts' parameter in the
amdgpu_vm_handle_fault function's comment block.

Fixes the below with gcc W=1:

It was generated from my patch "drm/amdkfd: Change kfd/svm page fault 
drain handling". kernel test robot <lkp@intel.com> also reported same. 
Please add:

If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot<lkp@intel.com>
| Closes:https://lore.kernel.org/oe-kbuild-all/202408251419.vgZHg3GV-lkp@intel.com/
