[PATCH] video: tc358767: set num_modes=0 if no valid mode found

[Andrey Gusakov]

Since commit f986661 "video: ipu: register framebuffer,
even when no modes are found" value returned from
VPL_GET_VIDEOMODES ioctl is ignored. So set valid num_modes
in error case to avoid crash in register_framebuffer.
