issue logs:
```
Running scenario 1
Error: Fail to find DMA 0000:f2:01.0.
Not enough dmadevs (0) for all workers (1).
Stopping dmadev 0
dma: Device 0 already stopped.
No proper operation for variable entry.
```

reason for failure: the device name is populated from `idxd_pci.c` as
`0000:f2:01.0-q0`

actions tried:
1. modified by forcing `--proc-type=3Dprimary`. same issue=20
2. modified name in ini `0000:f2:01.0-q0`, worked.

Checking the driver/dma/idxd_pci.c show cases the issue comes because the
application is identified as `RTE_SECONDARY`. attaching screen shot for the
same.
