Christian Mauderer f7a204e3d7 bsp/atsam/i2c: Add error return and fix edge cases ...

The driver didn't return with an error on (for example) a NACK on the
bus. This adds the expected error return. Due to the new case that a
transfer can be interrupted on an error, there were some new edge cases.
This patch therefore also fixes these edge cases by removing the
transfer_state that more or less duplicated the interrupt states.

Fixes #4591
