Vladis Dronov 7943d19453 drm/vmwgfx: limit the number of mip levels in vmw_gb_surface_define_ioctl() 
commit ee9c4e681e 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'.
