    libcli/smb: use conn->smb2.server.cipher != 0 instead of conn->smb2.server.capabilities & SMB2_CAP_ENCRYPTION
    
    SMB 3.10 servers don't report SMB2_CAP_ENCRYPTION anymore.
    So using conn->smb2.server.cipher != 0 is a more consistent way to decide if
    encryption is supported on the connection.
