driver/tcs3400: make error message in sensor read less spammy.
In EMULATED_IRQ_EVENT mode, we try to estimate the time between a read request and data ready. If the estimated time is shorter, an error message is printed to the console on every retry. On Kukui, this caused ec console spamming one line per second. Change the behavior to print only when returning error. No need to adjust the estimate time because one retry per read is still good enough. BUG=b:137345336 TEST=manually, verify that error message disappeared.
