mass_dns: only scale back for initial requests
...
Some requests just take longer; they may have lots of recursion or a
slow authoritative server. That won't change on retransmissions, so if
we treat all requests and retransmissions equally, we get a long tail of
retransmits with smaller and smaller capacity (parallelism). Instead, we
will use the initial-request period to determine server capacity and
then not change it during the retransmit phase.

This is the flag for the -R option. "always" is more appropriate than
"all," since "resolveall.nse" does something different, and there is a
"resolve_all" function that does that thing as well, unrelated to the -R
option.
