Indeed in accordance with the alloc_dma_desc_resources() method logic the Rx descriptors will be left allocated if Tx descriptors allocation fails. Fix it by calling the free_dma_rx_desc_resources() in case if the alloc_dma_tx_desc_resources() method returns non-zero value. While at it refactor the method a bit. Just move the Rx descriptors allocation method invocation out of the local variables declaration block and discard a pointless comment from there.
