Improve log message.

Add more information to the failure message: now it looks something like `Failed to get a callback for Display 0 switching from {Config 38: vsyncPeriod 4166666, minFrameIntervalNs 16666667} to {Config 37: vsyncPeriod 8333333, minFrameIntervalNs 8333333}` instead of `failed to get a callback for the display 0 with config 37`
