thermal/debugfs: Create records for cdev states as they get used
Because thermal_debug_cdev_state_update() only creates a duration record
for the old state of a cooling device, if its new state is used for the
first time, there will be no record for it and cdev_dt_seq_show() will
not print the duration information for it even though it contains code
to compute the duration value in that case.
Address this by making thermal_debug_cdev_state_update() create a
duration record for the new state if there is none.
