realtime: Remove printing of cpu affinity masks in pi-tests: Some tests under realtime/func/pi-tests in LTP display junk values for cpu affinity masks:
Start ./testpi-2
protocol in mutexattr is 1

testpi-1 and testpi-4 also report similar wrong values.
The cause of this problem is the incorrect way in which sched_getaffinity output is used in the tests. I think there is no need to call getaffinity() to know the cpu mask, because we test the return value of setaffinity() before that. The following patch removes all calls to sched_affinity() and removes printing cpu affinity masks.
