Dmitrii Gavrilov e55ec34d3e system/qdev-monitor: move drain_call_rcu call under if (!dev) in qmp_device_add() ...

Original goal of addition of drain_call_rcu to qmp_device_add was to cover
the failure case of qdev_device_add. It seems call of drain_call_rcu was
misplaced in 7bed89958b what led to waiting for pending RCU callbacks
under happy path too. What led to overall performance degradation of
qmp_device_add.

In this patch call of drain_call_rcu moved under handling of failure of
qdev_device_add.
