Inline the internal of bdev_nvme_delete_ctrlr() and bdev_nvme_failover()
into _bdev_nvme_delete().
Change the _nvme_ctrlr_destruct() call from direct to message passing
to reduce lock hold time and avoid potential deadlock.
Then, protect nbdev_ctrlr via g_bdev_mutex_unlock and each nvme_ctrlr
via nvme_ctrlr->mutex.
