spi: atmel: Add missing annotation for atmel_spi_next_xfer_dma_submit()

Sparse reports a warning at atmel_spi_next_xfer_dma_submit()

warning: context imbalance in atmel_spi_next_xfer_dma_submit()
	- unexpected unlock

The root cause is the missing annotation
	at atmel_spi_next_xfer_dma_submit()

Add the missing __must_hold(&as->lock) annotation
