Fate actions are different per domain.
When all the domains, ingress, egress and FDB (transfer),
can support all the policy actions, i.e. [SET_TAG],
the policy prepares resources for all the domains and
failure happens if one of the domains misses its fate action
in the policy action list.
Remove the domains missing their fate action
from the meter policy preparation.
Now, the policy will prepare a domain only when the domain supports
all the actions and when one of the domain fate actions is on the list.
Fixes: afb4aa4f12
