vmm: api: Match VhostUserBlkConfig defaults between CLI and HTTP API

Browse Source 
In order to let the CLI and the HTTP API behave the same regarding the
VhostUserBlkConfig structure, this patch defines some default values
for num_queues, queue_size and wce.

num_queues is 1, queue_size is 128 and wce is true.
