backends/dbus-vmstate: Fix short read error handling
When dbus_vmstate_post_load() fails, it complains to stderr. Except
on short read, where it checks with g_return_val_if_fail(). This
fails silently if G_DISABLE_CHECKS is undefined (it should be), or
else pads the short read with uninitialized bytes.
Replace g_return_val_if_fail() by a proper error check.
