    Correct the h_Enumerate_r hostList safety check
    
    Ide1e5aca7c2c4a4af3f62bc07821db694f2f9999 added safety checks for a few
    traversals through hostList, including the traversal in h_Enumerate_r.
    Unfortunately, h_Enumerate_r may not hold H_LOCK over its entire
    traversal (h_Release_r can drop and reacquire it), so the value of
    hostCount is not guaranteed to stay the same.
    
    A host may be deleted during the loop, or right near the end, decreasing
    hostCount to below our current running 'count' of hosts, triggering the
    panic unnecessarily. So instead, remember the value of hostCount.
