Subject: [PATCH] Fix a bad free on portfwd name resolution failure.

If name resolution fails, pfd_connect tries to sfree(dummy_realhost)
when it's completely uninitialised - the failed resolution didn't
write to it, and we also didn't precautionarily initialise it to NULL
first. Now we do the latter.
