Command 'perf record' calls:
cmd_report()
record__auxtrace_init()
auxtrace_record__init()
On s390 function auxtrace_record__init() returns random return value due
to missing initialization.
This sometime causes 'perf record' to exit immediately without error
message and creating a perf.data file.
Fix this by setting error the return code to zero before returning from
platform specific functions which may not set the error code in call
cases.
