Subject: [media] media: dvb-core: Don't force CAN_INVERSION_AUTO in oneshot mode

From: Malcolm Priestley <tvboxspy@gmail.com>

commit c9d57de6103e343f2d4e04ea8d9e417e10a24da7 upstream.

When in FE_TUNE_MODE_ONESHOT the frontend must report
the actual capabilities so user can take appropriate
action.

With frontends that can't do auto inversion this is done
by dvb-core automatically so CAN_INVERSION_AUTO is valid.

However, when in FE_TUNE_MODE_ONESHOT this is not true.

So only set FE_CAN_INVERSION_AUTO in modes other than
FE_TUNE_MODE_ONESHOT
