That's probably a mistake.  The bug isn't closed.

One of the suggested work-arounds in that bug report is to revert to an 
older version of dracut and rebuild your initrd.  You'd need to get:

dracut-network-033-535.el7.x86_64.rpm kexec-tools-2.0.15-13.el7.x86_64.rpm

...from the vault: http://vault.centos.org/7.5.1804/updates/x86_64/Packages/

Downgrade those packages, and then run "dracut -f" to rebuild the initrd 
for your kernel.
