s3: smbclient: Ensure we call client_clean_name() before all operations on remote pathnames.
This allows names containing .. components to be resolved on the client side before being sent to the server. Relative names work in SMB1 but not in SMB2. Fix both client.c and clitar.c BUG: https://bugzilla.samba.org/show_bug.cgi?id=13093 Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: Andreas Schneider <asn@samba.org>
