This patch fixes the check to set compliant offloading flag.
Compliant offloading flag should be set when the
'legacy-ol-flags' is true.

Fixes: 3a6ee8dafb21("net/vhost: enable compliant offloading mode")

Nack, legacy OL flags is NOT compliant. So current implementation is
good.

Sorry, it's a wrong fix, the compliant mode is enabled by default.
