From: Fiona Ebner <f.ebner@proxmox.com>

Commit 9876359990 ("hw/scsi/lsi53c895a: add timer to scripts
processing") reduced the maximum allowed instruction count by
a factor of 100 all the way down to 100.

This causes the "Check Point R81.20 Gaia" appliance [0] to fail to
boot after fully finishing the installation via the appliance's web
interface (there is already one reboot before that).

With a limit of 150, the appliance still fails to boot, while with a
limit of 200, it works. Bump to 500 to fix the regression and be on
the safe side.
