vsnprintf patch

[Adrian Reber <adrian@lisas.de>]

When using the snprintf function from the kernel the length returned is
not the length written:

len = snprintf(test,1,"BLA 1"); 

len is 5 although test is "B"

the patch below fixes the symptom, but I am not sure if this is the real
solution for this problem.
