Nouveau - Jan 2019 - [PATCH xf86-video-nouveau 1/2] xv: Avoid shadowed declaration of 'int i' in NVPutImage

int i is accessed outside immediate scope so leave declaration at
the highest common scope level:

  1073:  int ret, i;
         ...
         // Highest common scope
         ...
  1193:  if (newTTSize <= destination_buffer->size) {
           ...
           // Used in this scope
           ...
  1248:  } else {
           ...
           // Used in this scope
           ...
  1316:  }
         // Not used in this scope

Warning reported by gcc 8.2:

nouveau_xv.c: In function ‘NVPutImage’:
nouveau_xv.c:1195:7: warning: declaration of ‘i’ shadows a previous local
[-Wshadow]
   int i = 0;
       ^
nouveau_xv.c:1073:11: note: shadowed declaration is here
  int ret, i;
           ^
