[qarsh] Fix double-free and command hang

We need to test all exit conditions at once so we fall back into the
hbeat code.  I was falling into a case when running "reboot -fin &"
where the command would exit, but the sockets would not close and we
weren't getting to hbeat() to detect the reboot.

In another case which I can't completely explain, we were getting a
double-free error from glibc in the qpfree() at the end of
run_remote_cmd().  Instead of waiting until the very end to read the
exit status, save it off as soon as we get the packet and use
cmd_exitted to determine if we have an exit code or if something went
horribly wrong.
