dmaengine: fsl-edma: Fix clk leak on alloc_chan_resources failure
[ Upstream commit b18cd8b210417f90537d914ffb96e390c85a7379 ]
When fsl_edma_alloc_chan_resources() fails after clk_prepare_enable(),
the error paths only free IRQs and destroy the TCD pool, but forget to
call clk_disable_unprepare(). This causes the channel clock to remain
enabled, leaking power and resources.
Fix it by disabling the channel clock in the error unwind path.
