[PATCH v3 03/20] nvme-fabrics: Expose nvmf_check_required_opts() globally

From: Shai Malin <hidden>
Date: 2021-06-24 17:25:20
Subsystem: nvm express driver, the rest · Maintainers: Keith Busch, Jens Axboe, Christoph Hellwig, Sagi Grimberg, Linus Torvalds

From: Prabhakar Kushwaha <redacted>

nvmf_check_required_opts() is used to check if user provided opts has
the required_opts or not. if not, it will log which options are not
provided.

It can be leveraged by nvme-tcp-offload to check if provided opts are
supported by this specific offload driver or not.

So expose nvmf_check_required_opts() globally.
