download_internal is supposed to always set pm_errno but did not in many
cases.
The most important (and tested) change is the one concerning fetchStat. This
is typically where the code will fail when the network is down for example.
Before commit d2dbb04a9af7a18da, this fetchStat call did not exist and the
same kind of errors would be encountered in the fetchXGet call that follows.
I just copied the error printing to restore the old behavior.
