ASoC: rt715-sdca: Fix return value check in rt715_sdca_sdw_probe()

Browse Source 
In case of error, the function devm_regmap_init_sdw_mbq() and
devm_regmap_init_sdw() returns ERR_PTR() not NULL. The NULL test
in the return value check should be replaced with IS_ERR().

Fixes: 393c52d2d109 ("ASoC: rt715-sdca: Add RT715 sdca vendor-specific driver")
