nvmet: reorder fields in 'struct nvmet_sq'

Browse Source 
Group some variables based on their sizes to reduce holes.
On x86_64, this shrinks the size of 'struct nvmet_sq' from 472 to 464
bytes when CONFIG_NVME_TARGET_AUTH is defined.

This structure is embedded into some other structures, so it helps reducing
their sizes as well.
