[Mesa-dev] [PATCH v2 kmscube] cube-tex: Do not declare counter inside 'for' loop

[Fabio Estevam]

Do not declare counter inside 'for' loop to fix the following build errors
on mips64el:

cube-tex.c: In function 'get_fd_rgba':
cube-tex.c:230:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (uint32_t i = 0; i < texh; i++) {
  ^
cube-tex.c:230:2: note: use option -std=c99 or -std=gnu99 to compile your code
cube-tex.c: In function 'get_fd_y':
cube-tex.c:261:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (uint32_t i = 0; i < texh; i++) {
  ^
cube-tex.c: In function 'get_fd_uv':
cube-tex.c:292:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (uint32_t i = 0; i < texh/2; i++) {
  ^
