blake2s: remove NOSPLIT from asm functions

Now that the frame sizes of these functions are correct, the compiler
is detecting that they overflow the NOSPLIT stack. They don't need to
be NOSPLIT, so remove that flag.

This fixes the 1.7 build. The build is not broken at tip because the
stack guard is larger.
