igc: Set Qbv start_time and end_time to end_time if not being configured in GCL
The default setting of end_time minus start_time is whole 1 second.
Thus, if it's not being configured in any GCL entry then it will be
staying at original 1 second.
This patch is changing the start_time and end_time to be end_time as
if setting zero will be having weird HW behavior where the gate will
not be fully closed.
