Place HKDF info in to a temporary buffer if required.

If the info input overlaps with the output destination, copy
the info to a temporary buffer first. As the HKDF expansion
is performed, the output buffer is filled by hash size. However
this will overwrite the info, should the buffers overlap.

The other parameters, like prk, salt, and ikm do not need any addional
handling for overlaps.
