afs: make sure to call afs_Analyze after afs_Conn

The afs_Conn function is used to pick a connection for a given RPC. The
RPC is normally wrapped within a do-while loop which calls afs_Analyze
to handle the RPC code and manage the server connection references.
Among other things, afs_Analyze can mark the server as down, blacklist
idle servers, etc.

There are some special cases in which we break out of this do-while loop
early, by putting the connection reference given by afs_Conn and then
jumping out of the loop.

In these cases, be sure to call afs_Analyze to put the server connection
we got from afs_Conn, and to handle the RPC return code, possibly
marking the server as down or blacklisted.
