dmaengine: fsldma: Fix a resource leak in the remove function
[ Upstream commitcbc0ad004c
] A 'irq_dispose_mapping()' call is missing in the remove function. Add it. This is needed to undo the 'irq_of_parse_and_map() call from the probe function and already part of the error handling path of the probe function. It was added in the probe function only in commitd3f620b2c4
