Comment 5 for bug 1510976

@Denis, the issue is that we incorrectly detect exit code, since we always check `find` command result instead of `rsync` command result.

The impact is that if we have non-zero exit code for `rsync` command we'll never catch this because we have `find`.

In short incorrect flow:
1) rsync
2) find
3) check_rsync_code

but MUST be:

1) rsync
2) check_rsync_code
3) find
