From: Peter Maydell <peter.maydell@linaro.org>

In curl_open(), the 'out' label assumes that the state->errmsg string
has been set (either by curl_easy_perform() or by manually copying a
string into it); however if curl_init_state() fails we will jump to
that label without setting the string.  Add the missing error string
setup.

(We can't be specific about the cause of failure: the documentation
of curl_easy_init() just says "If this function returns NULL,
something went wrong".)
