nvme: allow unprivileged passthrough of Identify Controller 



Add unprivileged passthrough of the I/O Command Set Independent and I/O
Command Set Specific Identify Controller sub-command.

This will allow access to attributes (e.g. MDTS and WZSL) that are needed
to effectively form passthrough I/O to the /dev/ng* character devices.
