wh_server: fix server comm not initialized from config

wh_Server_Init never assigns server->comm from config->comm before
calling wh_CommServer_Init(server->comm, ...). That passes an
uninitialized (zeroed) pointer to wh_CommServer_Init and will likely crash
or behave incorrectly.

Suggested minimal fix
Assign server->comm = config->comm (and validate config->comm != NULL)
before calling wh_CommServer_Init.
