media: ttusb-dec: fix memory leak in ttusb_dec_exit_dvb()
[ Upstream commit 517a281338322ff8293f988771c98aaa7205e457 ]
Since dvb_frontend_detach() is not called in ttusb_dec_exit_dvb(),
which is called when the device is disconnected, dvb_frontend_free()
is not finally called.
This causes a memory leak just by repeatedly plugging and
unplugging the device.
Fix this issue by adding dvb_frontend_detach() to ttusb_dec_exit_dvb().
