Ming Lei 7ea6bf2e6c percpu_ref: don't refer to ref->data if it isn't allocated
We can't check ref->data->confirm_switch directly in __percpu_ref_exit(), since
ref->data may not be allocated in one not-initialized refcount.

Fixes: 2b0d3d3e4f ("percpu_ref: reduce memory footprint of percpu_ref in fast path")
