hwspinlock: omap: Emit only one error message for errors in .remove()

If a remove callback of a platform driver returns a non-zero value, the
driver core emits an error message, otherwise ignores the value and
completes unbinding the device.

As omap_hwspinlock_remove() already emits an error message, suppress the
core's error message by returning zero.
