i2c: Timeouts reach -1

commit a746b578d8406b2db0e9f0d040061bc1f78433cf upstream

With a postfix decrement these timeouts reach -1 rather than 0, but
after the loop it is tested whether they have become 0.

As pointed out by Jean Delvare, the condition we are waiting for should
also be tested before the timeout. With the current order, you could
exit with a timeout error while the job is actually done.
