    Function: SbReleaseLink

	Description
	-----------
    This function initates release of SPP link associated with the port number specified
    on the local device.
    
    This function waits on Mbox events untill simply blue CFM message and 
    link_released messages are processed.

	Arguments
	---------
    LocalPortNo  : port number of the local device

    Returns
	-------
    A SBStatus_T value indicating result of the operation.
