This is caused by the the ec2_ephemeralswap script; it broke when the SWAPMETA
VM zone went away.  I've disabled that script in the new AMI builds, but of
course if you have ec2_ephemeralswap_enable=YES in an instance you upgrade,
you'll see this error.

For now, just remove the ec2_ephemeralswap_enable line; some day I'll find
time to fix the script to work on recent FreeBSD (including working with the
newer "nvme" disks).
