perf data: Fail check_backup in case of error
And display the error message from removing the old data file:
$ perf record ls
Can't remove old data: Permission denied (perf.data.old)
Perf session creation failed.
$ perf record ls
Can't remove old data: Unknown file found (perf.data.old)
Perf session creation failed.
Not sure how to make fail the rename (after we successfully remove the
destination file/dir) to show the message, anyway let's have it there.
