i2c-pasemi: Fix NACK detection

patch be8a1f7cd4501c3b4b32543577a33aee6d2193ac in mainline.

Turns out we don't actually check the status to see if there was a
device out there to talk to, just if we had a timeout when doing so.

Add the proper check, so we don't falsly think there are devices
on the bus that are not there, etc.
