    Bug fix - Failed to deallocate PD - Device or resource busy #52
    
    Root cause - The code calls ibv_dealloc_pd without deregistering
    all MR’s associated with that PD. send_destroy_ctx calls destroy_ctx
    which doesn’t deregister the credit mr if rdma_cm is OFF.
    However, rdma_cm is set to off before calling send_destroy_ctx.
    
    Fix: Remove the line that sets the rdma_cm to OFF.
    The code deregisters the MR used for the CM.
