arch_supports_noncont_cat() checks if vendor is ARCH_AMD and if that is
not true, ARCH_INTEL is assumed which might not be true either because
get_vendor() can also return zero if neither AMD nor Intel is detected.
Generalize the vendor check using switch/case logic and return false
for unknown vendors.
