coresight: cti: Don't disable ect device if it's not enabled
If associated ect device is not enabled at first place, disable
routine should not be called. Add ect_enabled flag to check whether
ect device is enabled. Fix the issue in below case. Ect device is
not available when associated coresight device enabled and the
association is established after coresight device is enabled.
