[PATCH 4.12 06/22] nvme-fabrics: generate spec-compliant UUID NQNs

[Greg Kroah-Hartman]

4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Daniel Verkamp <daniel.verkamp@xxxxxxxxx>

commit 40a5fce495715c48c2e02668144e68a507ac5a30 upstream.

The default host NQN, which is generated based on the host's UUID,
does not follow the UUID-based NQN format laid out in the NVMe 1.3
specification.  Remove the "NVMf:" portion of the NQN to match the spec.
