nvme: fixing ctrlr mutex free

Browse Source 
adding nvme_ctrlr_destruct_finish because nvme_transport_ctrlr_destruct may
use a destroyed mutex.

nvme_ctrlr_destruct() free "ctrlr_lock" and after that call
nvme_transport_ctrlr_destruct()->nvme_pcie_ctrlr_destruct()(with pci)->
nvme_ctrlr_proc_get_devhandle()->nvme_robust_mutex_lock(&ctrlr->ctrlr_lock);
