[media] Mantis: use dvb_attach to avoid double dereferencing on module removal
Convert the driver to use the dvb_attach macro to avoid the hard dependency on the frontend drivers. The hard dependecy will result in loading a number of unused frontends, and unwanted automatic dereferencing. This fixes a bug where unloading the mantis driver will derefence any attached frontend twice, which will cause an oops if the same frontend is used by another driver.
