Code Issues Proposed changes

Update initrd with IPv6 improvements 

Patching content from upstream dracut for IPv6 improvements:
8061a43284
031e2f7bb8

These changes are present in the Centos8 initrd, but not Centos7.

The changes include:
- Addressing a race condition in the IPv6 DAD handling:
  https://bugzilla.redhat.com/show_bug.cgi?id=1765013
- Add a check for router advertise route (proto ra) prior to
  continuing with dracut init
