[PATCH 1/2] iso9660: Fix Forth return value for iso9660_files_open()

[Andreas Färber]

There's a mixup of 0 and -1. Don't return failure if iso9660_open() succeeded. Don't return success in case
iso9660_open() or iso9660_mount() failed.

This resolves both a hang when trying to boot cd:,\:tbxi and failure to boot either cd:,\ppc\bootinfo.txt
or cd:,\ppc\chrp\bootfile.exe despite present on the AIX 6.1 disk.
