[PATCH v4 2/4] dmaengine: dma-axi-dmac: Properly free struct axi_dmac_desc

["Nuno Sá via B4 Relay" <devnull+nuno.sa.analog.com@kernel.org>]

From: Nuno Sá <nuno.sa@analog.com>

Use axi_dmac_free_desc() to free fully the descriptor at fail path when
call axi_dmac_alloc_desc() in axi_dmac_prep_peripheral_dma_vec().

Fixes: 74609e568670 ("dmaengine: dma-axi-dmac: Implement device_prep_peripheral_dma_vec")
