[PATCH] ASoC: mediatek: Fix error handling

[Tang Bin]

If the function platform_get_irq() failed, the negative value
returned will not be detected here. So fix error handling in
mt6797_afe_pcm_dev_probe(). And when get irq failed, the function
platform_get_irq() logs an error message, so remove redundant
message here.
