monitor: Improve and document client_migrate_info protocol error 

Protocol must be spice, vnc isn't implemented.  Fix up documentation.

Attempts to use vnc or any other unknown protocol yield the misleading
error message "Invalid parameter 'protocol'".  Improve it to
"Parameter 'protocol' expects spice".
