do not enter vcpu again if it was stopped during IO
To prevent reentering vcpu after IO completion it is not enough
to set env->stopped since it is checked only in main loop but control
will not get there until next non-IO exit since kvm_run() will reenter
vcpu to complete IO instruction. Solve this by sending self-signal to
request exit after IO instruction completion.
