mm: swapfile: clean up unuse_pte race handling
The conditional mem_cgroup_cancel_charge_swapin() is a leftover from when the function would continue to reestablish the page even after mem_cgroup_try_charge_swapin() failed. After 85d9fc8 "memcg: fix refcnt handling at swapoff", the condition is always true when this code is reached.
