Use ALWAYS_FATAL if touchState is out of sync

Converting an existing LOG(FATAL) to LOG_ALWAYS_FATAL. This methods is
always called with tokens that hvae been added to touchstate. So in this
CL we
1. Rename the method accordingly.
2. Add a LOG_ALWAYS_FATAL for cases this expectation is not met.

This is a followup from ag/31432556.
