gstreamer: Do not lookup controls by id
The libcamerasrc element looks for the availability of the FrameDurationLimits control by looking it up by numeric control id. The ControlinfoMap::find(unsigned int i) function searches the control numerical identifier on the ContorlInfoMap::idMap_ class member, which might be not initialized if the pipeline handler does not register any control, causing an invalid memory access. Avoid looking up the control by numerical id and use the ControlId instance instead to prevent that.
