test_lru_sanity5() fails when the number of online cpus
is fewer than the number of possible cpus. It can be
reproduced with qemu by using cmd args "--smp cpus=2,maxcpus=8".
The problem is the loop in test_lru_sanity5() is testing
'i' which is incorrect.
This patch:
1. Make sched_next_online() always return -1 if it cannot
find a next cpu to schedule the process.
2. In test_lru_sanity5(), the parent process does
sched_setaffinity() first (through sched_next_online())
and the forked process will inherit it according to
the 'man sched_setaffinity'.
