udev does not allow an empty value for keys when importing output
from an external program. Providing an empty value for any key
invokes a warning during the parsing. Currently, ZDEV_SITE_ID for
fallback sites are not assigned any value. Add an empty double
quotes as the value in case of failover sites.
This modification is tested on udevadm version 253 on fedora38.
Also verify that the ZDEV_SITE_ID is properly written, if not log
the error.
Fixes: c8ad5f57d0 ("zdev: modify zdev_id to read the site_id from loadparm")
