    Windows: PrimaryVolumeWorkerThread Garbage Collect Fcb
    
    Revert commit cecd99abd3837ef820d78fb15e450c8688b0f39b.  Failing
    to garbage collect the FCB from the ObjectInformationCB at the
    earliest opportunity opens the door to a deadlock with Trend Micro's
    anti-virus driver.  Trend Micro attempts to make a copy of the
    file data each time a CcPurgeCacheSection() is performed on the
    FCB.  If during AFSValidateEntry or AFSVerifyEntry a DirectoryCB->
    ObjectInformationCB->FCB is discovered which has a non-NULL
    SectionObjectPointers.DataSectionObject and the data version in
    the DirEnumEntryCB differs from the ObjectInformationCB, a
    CcPurgeCacheSection() call is performed while holding the
    FCB->NPFcb->Resource exclusively.  Trend Micro will deadlock the
    thread making the CcPurgeCacheSection() call when it attempts
    to open the file in one of its worker threads.
