Timeout mechanism in WR FSM not very precise
WR mode should not be pursued after wrStateTimeout*wrStateRetry, with
wrStateTimeout=300ms and wrStateRetry=3, this should be 900ms.
The tester makes the timeout marginally greater than 900ms and the WR
FSM does not go to IDLE, instead it accepts the too late
message from the tester, i.e.
* reception times registered by WR Switch (912.722400ms):
Calibrate : 1523309683.328429648
Calibrated: 1523309684.241152048
* transmission times registered by TEE (913ms):
Calibrate : 11:51:46:698
Calibrated: 11:51:47:611
