[ Upstream commit 0f7ba7bc46 ]
A call to dma_alloc_coherent() is wrapped by sonic_alloc_descriptors().
This is correctly freed in the remove function, but not in the error
handling path of the probe function. Fix this by adding the missing
dma_free_coherent() call.
While at it, rename a label in order to be slightly more informative.
