PeakCAN: Do not set an error when receive buffer is empty

The function PeakCanBackendPrivate::startRead() reads
all incoming frames until the receive buffer becomes empty.

When the receive buffer is empty, the function should
exit silently. Otherwise, an error should be set up.

The previous code simply used the wrong constant to
allow this valid case.
