drm/vmwgfx: Zero initialize handle in vmw_execbuf_process
When building with -Wsometimes-uninitialized, Clang warns:
drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c:3964:7: warning: variable
'handle' is used uninitialized whenever '?:' condition is false
[-Wsometimes-uninitialized]
It's not wrong; however, in practice, this is never an issue because
the value of handle isn't used when user_fence_rep is NULL because
vmw_execbuf_copy_fence_user returns immediately when that is the case.
Just zero initialize this variable so that Clang no longer warns.
