spi: at91-usart: Remove some dead code
dma_request_chan() does not return NULL. It returns a valid pointer or an
error pointer.
So, some dead code can be removed.
The IS_ERR_OR_NULL() in the error handling path are still needed, because
the error handling path is common to the whole function and the
ctlr->dma_xx are NULL when at91_usart_spi_configure_dma() is called.
