+vhost-user: VHOST_USER_SET_MEM_TABLE doesn't contain all regions
+
+
+
+vhost-user implementation doesn't provide information about all memory regions, 
+and in some cases client is not able to map buffer memory as he is missing 
+memory region information for specific address.
+
+Same thing is implemented properly for vhost-net. Below gdb outputs are 
+showing memory regions information provided to the vhost-net and vhost-user.
