PATCH v2 1/1 timer: remove replay clock probe in deadline calculation

Ciro Santilli reported that commit a5ed352596a8b7eb2f9acce34371b944ac3056c4 breaks the execution replay. It happens due to the probing the clock for the new instances of iothread.
However, this probing was made in replay mode for the timer lists that are empty.
This patch removes clock probing in replay mode.
It is an artifact of the old version with another thread model.
