Similar to what commit 86dba8f3 did for virPortAllocatorRelease,
ignore port 0 in virPortAllocatorSetUsed.

For all the reasonable use cases the callers already check that
the port is non-zero, however if the port from the XML overflows
unsigned short and turns into 0, it can be set as used by
virPortAllocatorSetUsed but not released by virPortAllocatorRelease.

Also skip port '0' in virPortAllocatorSetUsed to make this behavior
symmetric.

The serenity was disturbed by commit 5dbda5e9 which started using
virPortAllocatorRelease instead of virPortAllocatorSetUsed (false).
