Restore ability to manually power down nodes, broken in 15.08.12
in commit b4904661

The patch introduced in commit b4904661 (not powering down dead node) has a bad side effect.  Adding the "(node_ptr->last_idle != 0)" condition prevents from powering down nodes with the following command:

scontrol update nodename=nX state=power_down

because the state update function relies on zeroing the "last_idle" variable when a power_down is requested (see src/slurmctld/node_mgr.c, line 1589).

Reverting this commit should solve the problem...but I let you decide...

bug 3093

node_features/knl_cray: If a node is rebooted outside of Slurm's direction,
    update it's active features with current MCDRAM and NUMA mode information.
bug 3071

Will be appended to usernames if --mail-user is not explicitly set for the
job and email notifications are requested.

Bug 3089.

Fix race condition that could result in MCDRAM state information coming
  from capmc rather than cnselect (used state for next boot rather than
  latest boot).
