Monitor/QMP: Don't allow cont on bad VM state
We have two states where issuing cont before system_reset can cause problems: RSTATE_SHUTDOWN (when -no-shutdown is used) and RSTATE_PANICKED (which only happens with kvm). This commit fixes that by doing the following when state is RSTATE_SHUTDOWN or RSTATE_PANICKED: 1. returning an error to the user/client if cont is issued 2. automatically transition to RSTATE_PAUSED during system_reset Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
