libcamera: camera: Fix unused variable compiler warning
When compiling with gcc 8.4.0, the compiler was reported to throw an unused variable warning: ../src/libcamera/camera.cpp: In member function ‘libcamera::CameraConfiguration::Status libcamera::CameraConfiguration::validateColorSpaces(libcamera::CameraConfiguration::ColorSpaceFlags)’: ../src/libcamera/camera.cpp:497:19: error: unused variable ‘i’ [-Werror=unused-variable] for (auto [i, cfg] : utils::enumerate(config_)) { ^ The build environment may have been incorrect as the problem couldn't be reproduced with gcc 8.3.0 and 8.5.0. Nonetheless, the 'i' variable is indeed unused. It turns out that the code can be simplified, as the commit that removed usage of the variable kept the now unneeded utils::enumerate() call. Simplify the code and fix the warning in one go.
