mod_anti_spam: Fix another traceback for origin sessions without an IP
This is likely to be the case for stanzas originating from local hosts, for
example (so not true s2s). It should be safe to bypass the IP check for those.

| 8 Introduction | |
| 9 ============ | |
| 10 | |
| 11 This module attemtps to provide a storage driver that is really multiple | |
| 12 storage drivers. This could be used for storage error tolerance or | |
| 13 caching of data in a faster storage driver. | |
| 14 | |
| 15 Configuration | |
| 16 ============= | |
| 17 | |
| 18 An example: | |
| 19 | |
| 20 ``` {.lua} | |
| 21 storage = "multi" | |
| 22 storage_multi_policy = "all" | |
| 23 storage_multi = { | |
| 24 "memory", | |
| 25 "internal", | |
| 26 "sql" | |
| 27 } | |
| 28 ``` | |
| 29 | |
| 30 Here data would be first read from or written to [mod\_storage\_memory], | |
| 31 then internal storage, then SQL storage. For reads, the first successful | |
| 32 read will be used. For writes, it depends on the `storage_multi_policy` | |
| 33 option. If set to `"all"`, then all storage backends must report success | |
| 34 for the write to be considered successful. Other options are `"one"` and | |
| 35 `"majority"`. |
