Make struct vhost_user_msg match the format defined in
the vhost-user spec. The custom additions were inhereted
from DPDK, but SPDK never made use of them. Also replace
direct sizeof(*msg) usages with a handy macro that was
already there. Finally add a VHOST_USER prefix to the
VHOST_MEMORY_MAX_NREGIONS #define.
