afs: Make it possible to find the volumes that are using a server

[ Upstream commit ca0e79a46097d54e4af46c67c852479d97af35bb ]

Make it possible to find the afs_volume structs that are using an
afs_server struct to aid in breaking volume callbacks.

The way this is done is that each afs_volume already has an array of
afs_server_entry records that point to the servers where that volume might
be found. An afs_volume backpointer and a list node is added to each entry
and each entry is then added to an RCU-traversable list on the afs_server
to which it points.

afs: fix the usage of read_seqbegin_or_lock() in afs_find_server*()

[ Upstream commit 1702e0654ca9a7bcd7c7619c8a5004db58945b71 ]

David Howells says:

(5) afs_find_server().

There could be a lot of servers in the list and each server can have
multiple addresses, so I think this would be better with an exclusive
second pass.

The server list isn't likely to change all that often, but when it does
change, there's a good chance several servers are going to be
added/removed one after the other. Further, this is only going to be
used for incoming cache management/callback requests from the server,
which hopefully aren't going to happen too often - but it is remotely
drivable.

(6) afs_find_server_by_uuid().

Similarly to (5), there could be a lot of servers to search through, but
they are in a tree not a flat list, so it should be faster to process.
Again, it's not likely to change that often and, again, when it does
change it's likely to involve multiple changes. This can be driven
remotely by an incoming cache management request but is mostly going to
be driven by setting up or reconfiguring a volume's server list -
something that also isn't likely to happen often.

Make the "seq" counter odd on the 2nd pass, otherwise read_seqbegin_or_lock()
never takes the lock.
