affs: rename local toupper() to fn() to avoid confusion

A compiler may see the collision with the toupper() defined in ctype.h:

 fs/affs/namei.c:159:19: warning: unused variable 'toupper' [-Wunused-variable]
   159 |         toupper_t toupper = affs_get_toupper(sb);

To prevent this from happening, rename toupper local variable to fn.

Initially this had been introduced by 24579a88 ("v2.4.3.5 -> v2.4.3.6")
in the history.git by history group.
