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.
