Proper bound check in _bfd_doprnt_scan

While an abort after storing out of bounds by one to an array in our
caller is probably OK in practice, it's better to check before storing.

PR 22397
* bfd.c (_bfd_doprnt_scan): Check args index before storing, not
after.

(cherry picked from commit 26a9301057457ae576b51b8127bb805b4e484a6b)
