Subject: cifs: fix smb1 mount regression
From: Paulo Alcantara <pc@xxxxxxxxxxxxx>
commit 72a7804a667eeac98888610521179f0418883158 upstream.
cifs.ko maps NT_STATUS_NOT_FOUND to -EIO when SMB1 servers couldn't
resolve referral paths. Proceed to tree connect when we get -EIO from
dfs_get_referral() as well.
