Add a new helper ACOMP_REQUEST_CLONE that will transform a stack
request into a dynamically allocated one if possible, and otherwise
switch it over to the sycnrhonous fallback transform. The intended
usage is:
ACOMP_STACK_ON_REQUEST(req, tfm);
...
err = crypto_acomp_compress(req);
/* The request cannot complete synchronously. */
if (err == -EAGAIN) {
/* This will not fail. */
req = ACOMP_REQUEST_CLONE(req, gfp);
/* Redo operation. */
err = crypto_acomp_compress(req);
}
