linux: up-enumerator-udev: Prevent reading the sysfs path from a non-GUdevDevice object

Browse source 
A non-GUdevDevice object may be included in the sibling device list,
since the udev information was created slowly. This object triggers
errors when upower tries to get udev information. Therefore,
get_latest_udev_device() returns NULL, when it receives a non-GUdevDevice
object.

The error messages are shown as follows:
(upowerd:2026931): GUdev-CRITICAL **: 10:38:29.775: g_udev_device_get_sysfs_path: assertion 'G_UDEV_IS_DEVICE (device)' failed

(upowerd:2026931): GUdev-CRITICAL **: 10:38:29.775: g_udev_client_query_by_sysfs_path: assertion 'sysfs_path != NULL' failed
