bdev/nvme: Factor out deleting secondary trid into a helper function

Browse Source 
Factor out deleting secondary trid from bdev_nvme_delete() into a
helper function bdev_nvme_delete_secondary_trid().

This will make the following changes simpler.

Besides, fix a typo, the case should be not 1B but 2B.
