spdk: fix ceph-osd crash when activate SPDK

When activate SPDK in Ceph, observe a Ceph crash.

It happened in the case 1) there is a pending IOContext in
NVMEDevice and 2) the lower block device has been recreated and
queue_t then points to an NVMEDevice that no longer exists.

This patch addresses the problem by deleting and zeroing queue_t
when NVMEDevice is closed.
