ASoC: cs42l51: Fix some error handling paths in cs42l51_probe()

Browse Source 
If devm_gpiod_get_optional() fails, we need to disable previously enabled
regulators, as done in the other error handling path of the function.

Also, gpiod_set_value_cansleep(, 1) needs to be called to undo a
potential gpiod_set_value_cansleep(, 0).
If the "reset" gpio is not defined, this additional call is just a no-op.

This behavior is the same as the one already in the .remove() function.
