icount: improve counting for record/replay

Browse source 
icount_warp_rt function is called by qemu_clock_warp and as
callback of icount_warp timer. This patch adds call to qemu_clock_warp
into main_loop_wait function, because icount warp may be missed
in record/replay mode, when CPU is sleeping.
This patch also disables of calling this function by timer, because
it is not needed after making modifications of main_loop_wait.
