This fixes bug introduced by multi-frontend to single-frontend change.
Finally HAS_LOCK is got back!
We are not allowed to access hardware in sleep mode...
Chip did not like when .get_frontend() reads some registers while
chip was sleeping and due to that HAS_LOCK bit was never gained.
TODO: We should add logic for dvb-core to drop out illegal calls like that.
