Disable HOGP only if it was previously enabled

bta_hh_cleanup_disable() is called to cleanup after the HID host and
HOGP host has been disabled. HOGP host must be disabled only if it was
enabled in first place. This change also allows us to remove
bta_hh_cleanup_disable callback from core interfaces. This interface
was used by GATT client because the HOGP host would unregister from
GATT even when it was not registered with GATT beforehand.
