platform/x86: lg-laptop: fix %s null argument warning

Browse Source 
[ Upstream commit e71c8481692582c70cdfd0996c20cdcc71e425d3 ]

W=1 warns about null argument to kprintf:
warning: ‘%s’ directive argument is null [-Wformat-overflow=]
pr_info("product: %s  year: %d\n", product, year);

Use "unknown" instead of NULL.
