The segment_close() callback is required to set ws_file to a negative value after closing a WAL segment, as documented in xlogreader.h. XLogReaderFree() only treated -1 as closed, so it could call segment_close() again if another negative value was used. This should not be an issue in practice, but all the other code paths in the tree use 0 as comparison base when dealing with ws_file, except for the line updated here. Let's be consistent, at least.
