fix assertion in QProcess/Win
Do not call bytesAvailableInChannel if the source pipe end is
invalid. This is the case when redirecting channels on Windows.
The assertions in bytesAvailableInChannel were triggered whenever
an output process or output file was set and waitForBytesWritten
was called.
Task-number: QTBUG-45548
