Ensure that the cm_req_t object is allocated and initialized at the
SMB layer for all incoming requests.  This is done for two reasons:

1. ensure that request start time is consistent across the lifetime
   of the request

2. permit the request object to be used to carry a flag indicating
   the source of the request.  This will permit different timeout
   algorithms to be used for SMB vs RDR in the future.
