NetworkPkg/DnsDxe: Fix zero StationIp configuration failure of DNSv6

Browse Source 
According UEFI Spec, set to zero StationIp means to let the underlying
IPv6 driver choose a source address. But currently, DNSv6 always return
EFI_NO_MAPPING. The issue is caused by below bugs in DnsDxe:
* Incorrect TPL(TPL_CALLBACK) usage during UDP configuration.
* Failed to create the timer used to get IPv6 mapping
* Doesn't check the Ip6Mode.IsStarted flag.
