[PATCH] uml: TT - SYSCALL_DEBUG - fix buglet introduced in cleanup
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.
