  cifs: update internal module number (2022-12-19 08:04:50 -0600)

As mentioned in the earlier smb3 client P/R, last week we were still
testing various additional important fixes: a series of DFS and reconnect
fixes from Paulo, which are now included in this P/R
----------------------------------------------------------------
20 cifs/smb3 client fixes, mostly related to reconnect and/or DFS

- two important reconnect fixes: cases where status of recently connected IPCs
and shares were not being updated leaving them in an incorrect state
- fix for older Windows servers that would return STATUS_OBJECT_NAME_INVALID
to query info requests on DFS links in a namespace that contained non-ASCII
characters, reducing number of wasted roundtrips.
- fix for leaked -ENOMEM to userspace when cifs.ko couldn't perform I/O due
to a disconnected server, expired or deleted session.
- removal of all unneeded DFS related mount option string parsing (now using
fs_context for automounts)
-improve clarity/readability, moving various DFS related functions out
of fs/cifs/connect.c
(which was getting too big to be readable) to new file.
- Fix problem when large number of DFS connections.  Allow sharing of DFS
connections and fix how the referral paths are matched
- Referral caching fix: Instead of looking up ipc connections to
refresh cached referrals,
store direct dfs root server's IPC pointer in new sessions so can
simply access it to
either refresh or create a new referral that such connections belong to.
- Fix to allow dfs root server's connections to also failover
- Optimized reconnect of nested DFS links
- Set correct status of IPC connections marked for reconnect
----------------------------------------------------------------
