ASoC: dmic: Fix check of return value from read of 'num-channels'
Commit 7fb59e940f62 ("ASoC: codecs: dmic: Make number of channels
configurable") introduces an optional property to the device tree
to specify the number of DMIC channels. dmic_codec_probe() uses
of_property_read_u32() to read the DT value, and expects a return
value of -ENOENT when the property does not exist. This expectation
is incorrect, the actual value returned in this case is -EINVAL (see
of_find_property_value_of_size(), which is called under the hood).
Check for -EINVAL instead.
