Subject: [PATCH 2/2] Fix: libpacemaker: avoid assertion failure if a
 node_state entry doesn't have an uname yet

It's possible that a node_state entry doesn't have an uname yet.
Previously in that case upon simulate_fencing_action(), crm_simulate
would encounter an assertion failure in pcmk__inject_node() at:
    CRM_ASSERT(rc == pcmk_ok);

, since a query by uname wouldn't find the existing node_state entry,
then the unnecessary creation of a new entry would conflict with the
existing one and a new query by uname would still get nothing.

This commit fixes it by finding the existing node_state entry by node id
and adding its uname to the entry rather than creating a new entry.
