MINOR: dns: enable caching of responses for server set by a SRV record

Browse Source 
The function srv_set_fqdn() is used to update a server's fqdn and set
accordingly its DNS resolution.
Current implementation prevents a server whose update is triggered by a
SRV record from being linked to an existing resolution in the cache (if
applicable).
This patch aims at fixing this.
