gianfar: Fix error in mdio reset timeout
The loop with the timeout used "while (... && timeout--)", which means than when the timeout occurs, "timeout" will be -1 after the loop has exited. The code that checks if the looped exited because of a timeout used "if (timeout <= 0)". Seems ok, except timeout is unsigned, and (unsigned)-1 isn't less than zero! Using "--timeout" in the loop fixes this problem, as now "timeout" will be 0 when the loop times out. This also fixes a bug in the existing code, where it will erroneously think a timeout occurred if the condition the loop was waiting for is satisfied on the final iteration before a timeout.
