glusterfs, gfapi: fix symbol clash
The callback structures in both protocol/client and glusterfsd, gfapi used the same name for the actor table - gluster_cbk_actors. CBKs are required only for the management connection, and the actors of protocol/client are NOP functions. This supposed-to-be NOP function dispatch tabble is actually ending up pointing to the actor table of glusterfsd or gfapi. These functions, even though set wrongly, are not even expected to be called through the protocol/client callback path. Glusterd however sends the FETCHSPEC (and other) notify callbacks to *all* connected clients unconditionally, and there is a small period of time when protocol/client is connected to glusterd for PORTMAP query. If the FETCHSPEC callback notify is issued in this window of time, we end up calling the wrong actor in the client side resulting in a crash.
