crypto: hctr2 - Convert to use POLYVAL library
The "hash function" in hctr2 is fixed at POLYVAL; it can never vary.
Just use the POLYVAL library, which is much easier to use than the
crypto_shash API. It's faster, uses fixed-size structs, and never fails
(all the functions return void).
Note that this eliminates the only known user of the polyval support in
crypto_shash. A later commit will remove support for polyval from
crypto_shash, given that the library API is sufficient.
