That is from 2013.  The EFI variable support code was subsequently
changed to work around common bugs in EFI implementations.  If you
still don't want efi-pstore, you can put efi-pstore.pstore_disable=Y on
the kernel command line.  But I don't think we're likely to change the
default again.

Older messages logged to EFI variables will be deleted automatically.

However I notice that your report says:

[...]

If this warning, or warnings, are logged at every boot, that might mean
that the variable space always gets filled up again before fwupd can
run.

Can you look back through the system log (dmesg or /var/log/messages)
to find the warning message?  We would need to see everything from
"WARNING" down to "end trace".
