[Qemu-devel] [PATCH v7 18/19] replay: init rtc after enabling the replay

[Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru>]

This patch postpones the call of 'configure_rtc' function. This call
uses host clock to configure the rtc, but host clock access should be
recorded when using icount record/replay mode. Therefore now rtc
is configured after switching record/replay mode on.
