[PATCH 2/2] ofono: Don't invoke SetProperty unnecessarily

When org.ofono.Modem.Powered property changes, connman invokes the
SetProperty method again with the new value.  This is pointless and
only creates unnecessary DBus traffic.

connmand[30]: plugins/ofono.c:modem_set_powered() /phonesim powered 1
connmand[30]: plugins/ofono.c:set_property() /phonesim path /phonesim org.ofono.Modem.Powered
connmand[30]: plugins/ofono.c:set_property_reply() /phonesim path /phonesim org.ofono.Modem.Powered
connmand[30]: plugins/ofono.c:modem_changed() /phonesim Powered 1
connmand[30]: plugins/ofono.c:modem_set_powered() /phonesim powered 1
connmand[30]: plugins/ofono.c:set_property() /phonesim path /phonesim org.ofono.Modem.Powered
connmand[30]: plugins/ofono.c:set_property_reply() /phonesim path /phonesim org.ofono.Modem.Powered

Fixes: 054dacc71c6a ("ofono: Set "powered" property according to value")
