Zhen Ni ce358252a9 dmaengine: fsl-edma: Fix clk leak on alloc_chan_resources failure 
[ Upstream commit b18cd8b210 ]

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.
