Comment out equality check in AbstractCompositeWriter.updateCurrent

There is a bug in ODL when checking auguments for equality:
https://git.opendaylight.org/gerrit/#/c/37719

Until the bug is fixed, updateCurrentAttributes will be invoked
even if there was no data change. It is customizer responsibility
to perform equality check if invoking update without actual data
change can cause side-effects in VPP.
