dmaengine: fsl-qdma: Fix a memory leak related to the queue command DMA
[ Upstream commit 3aa58cb51318e329d203857f7a191678e60bb714 ]
This dma_alloc_coherent() is undone neither in the remove function, nor in
the error handling path of fsl_qdma_probe().
Switch to the managed version to fix both issues.
