[FLINK-5553] keep the original throwable in PartitionRequestClientHandler
This way, when checking for a previous error in any input channel, we can
throw a meaningful exception instead of the inspecific
`IllegalStateException("There has been an error in the channel.")` before.
Note that the original `Throwable` (from an existing channel) may or may
not(!) have been printed by the `InputGate` yet. Any new input channel,
however, did not get the `Throwable` and must fail through the (now enhanced)
fallback mechanism.
