mm, swap: remove unneeded swap_extend_table_try_free() in swap_dup_entries_cluster()

Since commit 0475fde0f68de ("mm, swap: avoid leaving unused extend table
after alloc race"), extend table is always allocated when any swap count
reach MAX - 1 and is always freed when swap count decrease to MAX - 1 or
MAX - 2 with cluster lock held.  So the extend table will always be freed
properly when decrease swap count in __swap_cluster_put_entry().  So
swap_extend_table_try_free() outside of __swap_cluster_put_entry() is
unneeded and can be removed.
