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.
