mm: swap: use swap_entries_free() to free swap entry in swap_entry_put_locked()

In swap_entry_put_locked(), we will set slot to SWAP_HAS_CACHE before
using swap_entries_free() to do actual swap entry freeing.  This introduce
an unnecessary intermediate state.  By using swap_entries_free() in
swap_entry_put_locked(), we can eliminate the need to set slot to
SWAP_HAS_CACHE.  This change would make the behavior of
swap_entry_put_locked() more consistent with other put() operations which
will do actual free work after put last reference.
