Description: Car Node procedure list timer is expired, and a callback is being called. Inside the callback we are calling to CarNode_clearTimeoutProcedures which can be called from multiple places in the code. This function clears the procedure list and checks if there is any timer currently running by checking a global variable, and if so - abort it. In this case the global variable still holds the timer handle (which was just expired), therefore we call to BLEAppUtil_abortTimer, which frees the timer DB inside it. Then, the function call stack gets back to bleapputil_localTimerCB which called the callback function and free the same timer DB once again
