libcamera: controls: guard ControlInfoMap against nullptr idmap_
It's possible to construct a Camera with an unsafe controlInfo_. This is the case in the Simple pipeline, where the camera controls are not populated. With Simple, if we attempt to set a Control, we end up with a segfault because the default constructor for ControlInfoMap doesn't intialized idmap_ which is initialized at class declaration time as const ControlIdMap *idmap_ = nullptr; Add some safeguards in ControlInfoMap to handle this case.
