If 'mmc_of_parse()' fails, we must undo the previous 'dma_request_chan()'
call.

Fixes: abd37cccd47f ("mmc: mxs: use mmc_gpio_get_ro for detecting read-only status")
Signed-off-by: Christophe JAILLET <redacted>
Applied for next (by dropping the fixes tag as it seems non-critical
anyway), thanks!

Kind regards
