perf probe: Fix to free temporal Dwarf_Frame correctly
The commit 05c8d802fa52 ("perf probe: Fix to free temporal Dwarf_Frame")
tried to fix the memory leak of Dwarf_Frame, but it released the frame
at wrong point. Since the dwarf_frame_cfa(frame, &pf->fb_ops, &nops) can
return an address inside the frame data structure to pf->fb_ops, we can
not release the frame before using pf->fb_ops.
This reverts the commit and releases the frame afterwards (right before
returning from call_probe_finder) correctly.
