net: ethernet: sun4i-emac: Fix an error handling path in emac_probe()
A dma_request_chan() call is hidden in emac_configure_dma().
It must be released in the probe if an error occurs, as already done in
the remove function.
Add the corresponding dma_release_channel() call.
Fixes: 47869e82c8b8 ("sun4i-emac.c: add dma support")
