If pm_runtime_get() fails in .remove() the driver used to return the error to the driver core. The only effect of this (compared to returning zero) is a generic warning that the error value is ignored. (The device is unbound then anyhow.) Emit a better warning and return zero to suppress the generic (and little helpful) message. Also disable runtime PM in the error case. This prepares changing platform device remove callbacks to return void.
