Correct setting TX random backoff register. This register is
implemented as a 10 bits linear feedback shift register so only
lower 10 bits are valid.
Because this register is used to initialize random backoff interval
register only when resolved duplex is half-duplex, it wouldn't have
caused issues in these days.
