Xin Xiong fe0e2ce5c8 mtd: rawnand: atmel: fix refcount issue in atmel_nand_controller_init 
[ Upstream commit fecbd4a317 ]

The reference counting issue happens in several error handling paths
on a refcounted object "nc->dmac". In these paths, the function simply
returns the error code, forgetting to balance the reference count of
"nc->dmac", increased earlier by dma_request_channel(), which may
cause refcount leaks.

Fix it by decrementing the refcount of specific object in those error
paths.
