Fix RedisModule_IsAOFClient Redis Module API (#8596)
Fix RedisModule_IsAOFClient Redis Module API (#8596)

Since the API declared (as #define) in redismodule.h and uses
the CLIENT_ID_AOF that declared in the server.h, when
a module will want to make use of this API, it will get a compilation
error (module doesn't include the server.h).

The API was broken by d6eb3af (failed attempt for a cleanup).
Revert to the original version of RedisModule_IsAOFClient
that uses UINT64_MAX instead of CLIENT_ID_AOF
