3ff7e42074 Change behavior for fallback handling 
Fallback would do nothing to fix a persistent problem with an IPMI
session.  For lack of knowing how to avoid the situation, at least
make changes so it won't go wrong in the future.

0016077bee Ensure that wait_for_sync always does a new sync 
If a sync is in progress, wait for that to complete.

Then issue the requested *new* sync.

Probably only needed if fullsync, as the one in progress may be a
'dirty' only sync and fullsync would be satisfied by the partial sync
without it, which is bad.

c80ebb0e8d Explicitly close connection before replacement

61dd71778f Never generate new key on crypt read 
An autogenerated key on read can never be useful.  Instead, let it fail
and assume a repair action is coming.
