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

Fixes a bug introduced in commit e32dacb9f4 -
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.
