BUG/MINOR: dns: remove irrelevant dependency on a client connection

The do-resolve action tests for a client connection to the stream and
tries to get the client's address, otherwise it refrains from performing
the resolution. This really makes no sense at all and looks like an
earlier attempt at resolving the client's address to test that the
code was working. Further, it prevents the action from being used
from other places such as an autonomous applet for example, even if
at the moment this use case does not exist.

This patch simply removes the irrelevant test.

This can be backported to 2.0.
