Turn SRXAFSCB_InitCallBackState3() into the primary function for
processing InitCallBackStateX RPCs.  InitCallBackState3 accepts an
optional server uuid which can be used instead of the IP address
to locate a matching server object.  If the RPC comes from a server
that we know of, we can restrict the calback state initialization
to cm_scache_t objects on that file server.  If the request comes
from a server that we know nothing about and a uuid was specified,
we can ignore it.

During callback revocation, make use of the cell associated with
the server to restrict the revocation to cm_scache_t objects in
the one cell.  This is especially important for readonly volume
callbacks since volume ids are shared across multiple cells.

Add a missing case where the cm_volume_t cbExpiresRO time should
be set to the cm_scache_t cbExpires time.
