In case we loop on IRQ handler until stat is
finally zero, we would end up in a situation
where all I2C transfers would misteriously
timeout because we were not calling complete()
in that situation.

Fix the issue by moving omap_i2c_complete_cmd()
call inside the 'out' label.

Looks fine. Have you hit this issue in any corner case ?

in fact, yes. With a difficult to reproduce situation with drv2665 (one
of TI's piezo drivers) I saw that I was missing the ack and all
transfers were timing out ;-)
