r7148: Fix #2736: winbind race condition with detecting idle clients
winbind idle connection closing logic is getting invoked under high loads for
clients which may already have commands in the pipe. This race condition
causes clients to fail with NSS_STATUS_UNAVAIL sometimes. We now retry several
times hoping (still not guaranteed, though) it will work.
(This used to be commit 05c04cfd2526b8b9a82916b5dffc18bf27c3f198)
