If, while trying to claim a free logical address, a POLL message
times out, then abort this process. A CEC_TX_STATUS_TIMEOUT
should be handled the same as a CEC_TX_STATUS_ABORTED.

This avoids a situation where transmits time out due to a
driver or hardware bug and it takes ages before the attempt
to find available free logical addresses finishes.
