exec: drop cpu_can_do_io, just read cpu->can_do_io
After commit 626cf8f (icount: set can_do_io outside TB execution,
2014-12-08), can_do_io is set to 1 if not executing code. It is
no longer necessary to make this assumption in cpu_can_do_io.
It is also possible to remove the use_icount test, simply by
never setting cpu->can_do_io to 0 unless use_icount is true.
With these changes cpu_can_do_io boils down to a read of
cpu->can_do_io.
