aos: Make SetCurrentThreadAffinity errors a bit nicer
When the SetCurrentThreadAffinity call fails, it prints this error
message:
Check failed: sched_setaffinity(0, sizeof(cpuset), &cpuset) == 0: Invalid argument [22]
It doesn't actually tell you what CPUs you tried to set. That can make
debugging harder. This patch fixes that by enhancing the error message
to print the set of CPUs that were pass in.
