vgimportdevices: change result when devices are not added
When using --all, if one VG is skipped, continue adding other VGs, and do not return an error from the command if some VGs are added. (A VG is skipped if it's missing PVs.) If the command fails during devices file setup or device scanning, then remove the devices file if it has been newly created by the command, and exit with an error. If devices from a named VG are not imported (e.g. the VG is missing devices), then remove the devices file if it has been newly created by the command, and exit with an error. If --all VGs are being imported, and no devices are found to include in the devices file, then remove the devices file if it has been newly created by the command, and exit with an error.
