while i could query NM for it's connection state, and inhibit if it's
"connecting", i'm uncomfortable with that.  i've seen cases where
the laptop will stay in that state forever on an AP, apparently never
timing out.  (i'll investigate more next time i see this.)  NM also
always passes through the "disconnected" state on the way to "connecting"
right after a wakeup, and it's that state that is excessively long
when #9854 is happening.  so it's hard to tell a real disconnected from
a "transient" disconnected.

i think the right solution, at least until we understand the root
cause of #9854, is simply to inhibit idle suspend for a full 60
seconds after waking from led or power button sleep.  this change
will appear in the next release of powerd (22, i think).
