Fix subtle validation bug on TXT and SRV records.

SRV records would fail if entered as "_service._protocol" without the
domain. Move the domain coercion up above the check for _service._protocol
so its regex has a domain to chew on.

TXT records did not have any domain-part validation; you could end up
with bare-hostname TXT records instead of the correct hostname.domain
records. This only affects forward zones since TXT in reverse zones are
attached to an IP, which is validated as such elsewhere.
