Revert previous tweaks

As we migrate to the new to_xfer_partial interface, some of previous
tweaks become unnecessary, we don't have to check traceframe is
selected in each target implementation, so this patch below is
reverted.

  [PATCH] Send qXfer:traceframe-info:read when traceframe is selected.
  https://sourceware.org/ml/gdb-patches/2013-10/msg00752.html

Third, to_traceframe_info is only called when traceframe is selected,
that means it is only called when target is remote, tfile or ctf, so
this patch can be partially reverted,
