[PATCH] ASoC: loongson: fix error release

[tangbin <tangbin@xxxxxxxxxxxxxxxxxxxx>]

In function loongson_card_parse_of(), when get device_node
'codec' failed, the function of_node_put(codec) should not
be invoked, thus fix error release.

Fixes: d24028606e76 ("ASoC: loongson: Add Loongson ASoC Sound Card Support")
