requester: instance-id: Release read lock on conflict

36af84cdbb66 ("requester: Add new APIs for instance ID allocation and
freeing") introduced the new instance ID allocation APIs, and some
unbalanced locking along with it. When a conflict arose on an instance
ID, the read lock was not released by the non-owning caller.

Release the lock on conflict and on error, and add a test case to
prevent regression.
