i2c: stm32: fix the device used for the DMA map

Browse source

commit c870cbbd71 upstream.

If the DMA mapping failed, it produced an error log with the wrong
device name:
"stm32-dma3 40400000.dma-controller: rejecting DMA map of vmalloc memory"
Fix this issue by replacing the dev with the I2C dev.
