Subject[PATCH v9 04/12] nvmet: make nvmet_copy_ns_identifier() non-static
This function will be needed by the upcoming passthru code.

Passthru will need an emulated version of identify_desclist which
copies the eui64, uuid and nguid from the passed-thru controller into
the request SGL.

[chaitanya.kulkarni@wdc.com: this was factored out of a patch
