Correct policy action for reserve/unreserve volume actions

This PS corrects the policy action for reserve and unreserve
volume actions. There are a few policy actions that currently
have the wrong name. This PS is a pre-requsite for removing
strict_policy_enforce Patrole configuration option in order
to avoid false positives (e.g. a non-existent policy action
being validated against an API).

The os-reserve volume actions actually enforces
"volume_extension:volume_actions:reserve" and os-unreserve
actually enforces "volume_extension:volume_actions:reserve" [0].
