CIFS: Fix a possible invalid memory access in smb2_query_symlink() During following a symbolic link we received err_buf from SMB2_open(). While the validity of SMB2 error response is checked previously in smb2_check_message() a symbolic link payload is not checked at all. Fix it by adding such checks.
