Documentation/filesystems/seq_file.txt: create_proc_entry deprecated

This patch adds information for kernel 3.10 and above

+
+Note that the above article uses create_proc_entry which was removed in
+kernel 3.10. Current versions require the following update
+
+-       entry = create_proc_entry("sequence", 0, NULL);
+-       if (entry)
+-               entry->proc_fops = &ct_file_ops;
++       entry = proc_create("sequence", 0, NULL, &ct_file_ops);
