[PATCH 4/8] i2c: omap: also complete() when stat becomes zero

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.
