nvme: Check for Security send/recv support before issuing commands.
We need to verify that the controller supports the security commands before actually trying to issue them. Signed-off-by: Scott Bauer <scott.bauer@intel.com> [hch: moved the check so that we don't call into the OPAL code if not supported] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@fb.com>
