i2c: sprd: Delete i2c adapter in .remove's error path
If pm runtime resume fails the .remove callback used to exit early. This resulted in an error message by the driver core but the device gets removed anyhow. This lets the registered i2c adapter stay around with an unbound parent device. So only skip clk disabling if resume failed, but do delete the adapter.
