Fix perftest device init

[AndrewGavril]

Perftest sees the device, but cant open it

root@qemux86-64:/sys/kernel/debug# ibv_devices 
    device          	   node GUID
    ------          	----------------
    iwp0s3          	9a150bce93c33a74

root@qemux86-64:/sys/kernel/debug# ibv_devinfo 
Failed to open device

root@qemux86-64:/sys/kernel/debug# ib_send_lat   
 Couldn't get context for the device
 Couldn't get context for the device

May be caused by unimplemented operations:

For me, the device isn't listed at all:

# ibv_devices 
    device          	  node GUID
    ------          	----------------

ntb_transport reports the following:

[    1.872673] ntb_transport 0000:00:03.0: Inbound MW based NTB API is required
[    1.874456] ntb_transport: probe of 0000:00:03.0 failed with error -22

Have you loaded ntrdma module using modprobe ntrdma?
