Subject: [PATCH 5/6] soc: fsl: dpio: Suppress duplicated error reporting on device remove

Returning an error code from a fsl_mc_driver's remove callback results
in a generic error message, otherwise the value is ignored and the device
gets unbound.

As the only error path in dpaa2_dpio_remove() already emits an error
message, return zero unconditionally to suppress another (less helpful)
error report.
