upstream: when decompressing zlib compressed packets, use 

Z_SYNC_FLUSH instead of Z_PARTIAL_FLUSH as the latter is not actually
specified as a valid mode for inflate(). There should be no practical change
in behaviour as the compression side ensures a flush that should make all
data available to the receiver in all cases.
