Subject: CIFS: Improve readdir verbosity

From: Pavel Shilovsky <[email protected]>

commit dcd87838c06f05ab7650b249ebf0d5b57ae63e1e upstream.

Downgrade the loglevel for SMB2 to prevent filling the log with messages if e.g. readdir was interrupted. Also make SMB2 and SMB1 codepaths do the same logging during readdir.
