drm/vmwgfx: limit the number of mip levels in vmw_gb_surface_define_ioctl()
commit ee9c4e681ec4f58e42a83cb0c22a0289ade1aacf upstream.
The 'req->mip_levels' parameter in vmw_gb_surface_define_ioctl() is
a user-controlled 'uint32_t' value which is used as a loop count limit.
This can lead to a kernel lockup and DoS. Add check for 'req->mip_levels'.
