[PATCH 5/8] uml: TT - SYSCALL_DEBUG - fix buglet introduced in cleanup

["Paolo 'Blaisorblade' Giarrusso" <blaisorblade@yahoo.it>]

Fixes a bug introduced in commit e32dacb9f481fd6decb41adb28e720c923d34f54 -
index is initialized based on syscall before syscall is calculated.

I'm bothering with this mainly because it gives a correct warning when the config
option is enabled, even if the code is for a almost unused debugging option.
