Revert "Name reverse functional association "functional""

This reverts commit f9ae45d2f300349bd8d5c8947f16fceb107b602e.

The functional association goes away after activating a new image
(issue openbmc/openbmc#3038). The workaround is to keep the reverse
association names the same for the active and functional ones
until the issue is resolved.
