This gets around the setjmp thumb2 issue during compilation.

They were

When the BE_COMPLIANT_USE_LINEAR16 switch is set to False, causing
the (non-standard-compliant) LINEAR11 to be used for the output
voltage instead of LINEAR16, the mode field of the VOUT_MODE register
shall return an invalid value (3'b111) to indicate non-compliance.

Previously, a failed I2C transaction would leave the data buffer
intact, and if one didn't look at the return status they might assume
valid data were returned. This modification should make it easier to
identify failed transactions.
