drm/amdgpu: Potential uninitialized variable in amdgpu_vm_update_directories()

Browse Source 
commit 78aa02c713 upstream.

After commit ea09729c93 ("drm/amdgpu: rework page directory filling
v2") then it becomes a lot harder to verify that "r" is initialized.  My
static checker complains and so I've reviewed the code.  It does look
like it might be buggy... Anyway, it doesn't hurt to set "r" to zero
at the start.
