slub: drop bogus inline for fixup_red_left()

With m68k-linux-gnu-gcc-4.1:

    include/linux/slub_def.h:126: warning: `fixup_red_left' declared inline after being called
    include/linux/slub_def.h:126: warning: previous declaration of `fixup_red_left' was here

Commit c146a2b9 ("mm, kasan: account for object redzone in SLUB's
nearest_obj()") made fixup_red_left() global, but forgot to remove the
inline keyword.
