set ERROR state when scheduler hits max attempts

Presently when scheduler raises NoValidHost due to max attempts
being reached, the instance remains in a build state.
Exception handler for NoValidHost in manager.run_instance() needs
request_spec[instance_uuids] to know which host to put into an
error state in _set_vm_state_and_notify().
schedule_run_instances() was popping instance_uuids from the
request_spec prior to a call to _schedule().
Changed pop of instance_uuids prior to call to _schedule() to be a get.
Added pop of instance_uuids to beneath call to _schedule() as
individual creates do not need them.
