Bluetooth: Don't force DISCOVERY_STOPPED state in inquiry_cache_flush
We are not supposed to force DISCOVERY_STOPPED in inquiry_cache_flush
because we may break the discovery state machine. For instance, during

machine forcibly goes to DISCOVERY_STOPPED while it should stay in
DISCOVERY_FINDING state.
This problem results in unexpected behaviors such as sending two
mgmt_discovering events to userspace (when only one event is expected)
and Stop Discovery failures.
