[PATCH] PR libstdc++/86954 use non-placement operator delete

[Jonathan Wakely]

As explained in the PR, there's no reason to call the nothrow delete,
we can just use the normal one.

        * include/bits/stl_tempbuf.h (return_temporary_buffer): Use
        non-placement delete.

Tested x86_64-linux, committed to trunk.
