mmc: bcm2835: Fix DMA channel leak on probe error
commit 8c9620b1cc9b69e82fa8d4081d646d0016b602e7 upstream.
The BCM2835 MMC host driver requests a DMA channel on probe but neglects
to release the channel in the probe error path. The channel may
therefore be leaked, in particular if devm_clk_get() causes probe
deferral. Fix it.
