Initialize GError* to NULL before calling g_dbus_proxy_new_syn

This fixes the crash issue of power_control when manually build and
replace executable or library.
The reason why it does not crash on a full OpenBMC build may be due to
the prelink clear the stack (not sure).

Fixes openbmc/openbmc#818.
