bdev/nvme: Register nvme_bdev_ctrlr to the argument of the timeout callback

Browse Source 
This change removes the necessity to get nvme_bdev_ctrlr by calling
nvme_bdev_ctrlr_get_by_name() and simplifies the code.

bdev_nvme_reset() checks if nvme_bdev_ctrlr->destruct is false first.

Hence we will not degrade stability.
