cifs: do not attempt cifs operation on smb2+ rename error

commit 652727bbe1b17993636346716ae5867627793647 upstream.

A path-based rename returning EBUSY will incorrectly try opening
the file with a cifs (NT Create AndX) operation on an smb2+ mount,
which causes the server to force a session close.

If the mount is smb2+, skip the fallback.
