Christophe JAILLET 0f5335e158 nvmet: reorder fields in 'struct nvme_dhchap_queue_context' ...

Group some variables based on their sizes to reduce holes.
On x86_64, this shrinks the size of 'struct nvme_dhchap_queue_context' from
416 to 400 bytes.

This structure is kvcalloc()'ed in nvme_auth_init_ctrl(), so it is likely
that the allocation can be relatively big. Saving 16 bytes per structure
may might a slight difference.
