BGP link descriptor cannot have multiple 'MultiTopologyId TLV'

In protocols/bgp/bgpio/src/main/java/org/onosproject/bgpio/protocol/linkstate/BgpLinkLSIdentifier.java,

'parseLinkDescriptors' can parse multiple number of 'MultiTopologyId TLV' in a link descriptor, because 'count' has ambiguous operation and assignment (' count = count++; ')

-----------------------------------------------------------------------------------------------------------------------------------------------------------------
public static LinkedList<BgpValueType> parseLinkDescriptors(ChannelBuffer cb) throws BgpParseException {
...
int count = 0;

while (cb.readableBytes() > 0) {
...
case BgpAttrNodeMultiTopologyId.ATTRNODE_MULTITOPOLOGY:
...
count = count++; // ambiguous operation and assignment
//MultiTopologyId TLV cannot repeat more than once
if (count > 1)

...
}
...
}
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result of above operation, count will be always '0' and it can parse and add multiple number of 'MultiTopologyId TLV' in a link descriptor.
