[PATCH] ASoC: rockchip: Fix an error handling in 'rockchip_i2s_probe'

[Christophe JAILLET]

If this memory allocation fail, we must disable what has been enabled.
Do not return immediately but go thrue the error handling path instead.

Also use 'devm_kmemdup' instead of 'devm_kzalloc+memcpy' to simplify code.
