net: phy: mdio-bcm-unimac: remove redundant !timeout check
The check for zero timeout is always true at the end of the proceeding while loop; the only other exit path in the loop is if the unimac MDIO is not busy. Remove the redundant zero timeout check and always return -ETIMEDOUT on this timeout return path.
