David Sterba bbf703bfd3 btrfs-progs: crypto: call sha256 implementations by pointer
Change how sha256 implementation is selected. Instead of an if-else
check in the block processing function select the best version and assign
the function pointer. This is slightly faster.

At this point the selection is not implemented properly in
hash-speedtest so all results are from the fastest version. This will
be fixed once all algorithms are converted.
