xinhui pan a1348526a3 kfdtest: make p2ptest go through all gpus ...

Implement sDMA copy packet broadcast.

Each time sDMA will copy its local vram to sysbuf and next GPU's vram.
That will verify where the p2p link is broken.
Currently we just test push of p2p.

test result on 2 cpus, 4 gpus, numa enabled system.
[ RUN      ] KFDQMTest.P2PTest
[          ] Test 2 -> 3
[          ] PASS 2 -> 3
[          ] Test 3 -> 4
[          ] PASS 3 -> 4
[          ] Test 4 -> 5
[          ] PASS 4 -> 5
[          ] Test 5 -> 0
[          ] PASS 5 -> 0
[       OK ] KFDQMTest.P2PTest (190 ms)
