avr32: clean up memory allocation in at32_add_device_mci

This patch will check if the kzalloc for the MCI DMA struct actually
returns a valid address, and also clean up properly if it fails or the
function fails at a later stage.

This also silences a compiler warning about using the slave variable
uninitialized.
