nvme/cmb_copy: disable submission queue in CMB

Browse Source 
Recent CMB changes disable using the CMB copy and submission queue
at the same time, so disable use_cmb_sqs by default.

Also spdk_nvme_ctrlr_map_cmb() changed the "size" parameter used as
size of buffer that was mapped, so change it here too.
