slab: mark slab->obj_exts allocation failures unconditionally
commit f7381b9116407ba2a429977c80ff8df953ea9354 upstream.
alloc_slab_obj_exts() should mark failed obj_exts vector allocations
independent on whether the vector is being allocated for a new or an
existing slab. Current implementation skips doing this for existing
slabs. Fix this by marking failed allocations unconditionally.
Fixes: 09c46563ff6d ("codetag: debug: introduce OBJEXTS_ALLOC_FAIL to mark failed slab_ext allocations")
