Meetakshi Setiya 5fe671caed smb: client: sync the root session and superblock context passwords before automounting 
commit 20b1aa9123 upstream.

In some cases, when password2 becomes the working password, the
client swaps the two password fields in the root session struct, but
not in the smb3_fs_context struct in cifs_sb. DFS automounts inherit
fs context from their parent mounts. Therefore, they might end up
getting the passwords in the stale order.
The automount should succeed, because the mount function will end up
retrying with the actual password anyway. But to reduce these
unnecessary session setup retries for automounts, we can sync the
parent context's passwords with the root session's passwords before
duplicating it to the child's fs context.
