 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 #4592
