    smb: Fix IPv6 uri handling
    
    IPv6 server includes brackets in GMountSpec, smbclient doesn't. Remove
    the brackets from the uri before usage in smbclient functions.
    
    The IPv6 uris can be consequently used in the following format (port
    isn't mandatory), e.g.:
    gvfs-mount smb://[::1]:139/
