Fix crash after closing of ejected device on Linux

When the user calls QSP::close() in a slot which is connected to the
QSP::error() signal, then the application is crashed. The reason is that
we emit the QSP::error() signal before than we call QRingBuffer::chop()
of an internal read buffer, which becomes invalid after the
QIODevice::close() called. Therefore, we need just call
QRingBuffer::chop() before than the QSP::error() signal will be emitted.
