replay: use CF_NOIRQ for special exception-replaying TB

Browse Source 
Commit aff0e204cb1f1c036a496c94c15f5dfafcd9b4b4 introduced CF_NOIRQ usage,
but one case was forgotten. Record/replay uses one special TB which is not
really executed, but used to cause a correct exception in replay mode.
This patch adds CF_NOIRQ flag for such block.
