ipv6: sr: Use HMAC-SHA1 and HMAC-SHA256 library functions
Use the HMAC-SHA1 and HMAC-SHA256 library functions instead of
crypto_shash. This is simpler and faster. Pre-allocating per-CPU hash
transformation objects and descriptors is no longer needed, and a
microbenchmark on x86_64 shows seg6_hmac_compute() (with HMAC-SHA256)
dropping from ~2494 cycles to ~1978 cycles, a 20% improvement.
