net: phy: mdio-bcm-unimac: fix unsigned wrap-around when decrementing timeout
Change post-decrement compare to pre-decrement to avoid an
unsigned integer wrap-around on timeout. This leads to the following
!timeout check to never to be true so -ETIMEDOUT is never returned.
Detected by CoverityScan, CID#1452623 ("Logically dead code")
