Move EUS-only check earlier to avoid unnecessary work

Check if advisory only affects EUS products immediately after
verifying vulnerabilities exist, before extracting packages,
CVEs, and other data. This saves processing time for advisories
that will be skipped anyway.

Also cleaned up redundant product_full_name variable.
