drm/amdkfd: fix loop error handling

Browse Source 
Clang static analysis reports this problem
kfd_chardev.c:2594:16: warning: The expression is an uninitialized value.
  The computed value will also be garbage
        while (ret && i--) {
                      ^~~

i is a loop variable and this block unwinds a problem in the loop.
When the error happens before the loop, this value is garbage.
Move the initialization of i to its decalaration.
