    [NTOS:PS] Dereference the quota block during process cleanup
    
    Ensure that when we're cleaning up the EPROCESS object, that we are dereferencing
the quota block the process in question was using. The routine will automatically request
a quota block cleanup if the process that dereferenced the quota block was the last.
