    Fix symlink target in query_info_reply() for sftp backend
    
    In SSH_FXP_NAME messages, the name field is preceded by a uint32
    count field. query_info_reply() in gvfsbackendsftp.c did not take
    the existence of the count field into account, and so set symlink
    targets incorrectly.
    
    For a simple demonstration, use gvfs-info to stat a symlink on an
    ssh mount.
