i2c: sprd: Delete i2c adapter in .remove's error path
[ Upstream commit ca0aa17f2db3468fd017038d23a78e17388e2f67 ]
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.
