  cifs: update cifs_ses::ip_addr after failover (2022-06-24 13:34:28 -0500)

----------------------------------------------------------------
7 SMB3 fixes, addressing important multichannel, reconnect issues.
Multichannel mounts when the server network interfaces changed, or
ip addresses changed, uncovered problems, especially in reconnect, but
the patches for this were held up until recently due to some lock conflicts
that are now addressed.   Included in this set of fixes:

- 3 fixes relating to multichannel reconnect, dynamically adjusting the list of
server interfaces to avoid problems during reconnect
- a lock conflict fix related to the above
- 2 important fixes for negotiate on secondary channels (null netname can
unintentionally cause multichannel to be disabled to some servers)
- a reconnect fix (reporting incorrect IP address in some cases)
