Malformed address warnings in 2.5.6 rsyncd.log

[John Van Essen]

Non-numeric tokens in the hosts allow list (and prolly the deny list as 
well) in rsyncd.conf generate "malformed address" warnings in rsyncd.log.

In 2.5.5, there was a check to prevent trying to match the IP address
against access list tokens that did not have a digit as the first 
character.  That check is missing in 2.5.6.

Here's the patch to fix the problem (using a slightly different check):
