[PATCH 1/1] spi: ingenic: remove dmaengine_desc_free()

[Frank.Li@oss.nxp.com]

From: Frank Li <Frank.Li@nxp.com>

dmaengine_desc_free() is designed for DMA_CTRL_REUSE. If DMA_CTRL_REUSE
is not set, dmaengine_desc_free() will return -EPERM.

	if (!dmaengine_desc_test_reuse(desc))
		return -EPERM;

So calling dmaengine_desc_free() does nothing.
dmaengine_terminate_(a)sync() will free all already allocated descriptors.
