imp 7848664844 Report the Host Buffer Memory minimum and preferred sizes. 
The Host Buffer feature (NVMe 1.4 section 89) allows for the NVMe card
request the host provide it buffer for lookaside tables and maybe
other things. Report the card's minimum and preferred sizes with
nvmecontrol/camcontrol identify.
