This patch breaks the execution recording.
While vCPU tries to lock replay mutex in main while loop,
vga causes dirty memory sync and do_run_on_cpu call.
This call waits for vCPU to process the work queue.

There is one more fix.
Sometimes replay cannot continue after stopping/restarting of the virtual
machine.
This happens because warp on stopped machine and on running machine behaves
differently.
Timers deadline calculation depends on enabled flag of the virtual timer.
