Bjørn Mork a22407faba [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.
