From: Ronnie Sahlberg <lsahlber@xxxxxxxxxx>
commit e6d0fb7b34f264f72c33053558a360a6a734905e upstream.
If we enter smb2_query_symlink() for something that is not a symlink
and where the SMB2_open() would succeed we would never end up
closing this handle and would thus leak a handle on the server.
Fix this by immediately calling SMB2_close() on successfull open.
