dmaengine: at_xdmac: Replace two if statements with only one with two conditions

Browse Source 
Add a cosmetic change and replace two if statements with a single if
statement with two conditions. In case the optional txstate parameter is
NULL, we return the dma_cookie_status, which is fine, no functional change
required.
