TurboJPEG: Update JPEG buf ptrs on comp/xform err

When using the in-memory destination manager, it is necessary to
explicitly call the destination manager's term_destination() method if
an error occurs.  That method is called by jpeg_finish_compress() but
not by jpeg_abort_compress().

This fixes a potential double free() that could occur if tjCompress*()
or tjTransform() returned an error and the calling application tried to
clean up a JPEG buffer that was dynamically re-allocated by one of those
functions.
