mds/quiesce: prevent an overflow of the wait duration

QuiesceTimeInterval::max() may overflow inside of a call to
std::condition_variable::wait_for and result in a busy-loop,
making the call to timeout immediately

The solution is to cap the wait duration to a value which can
certainly fit in whichever clock std library is using internally.
