pkg/(crypto|vm): fix GolangCI errcheck warnings

Browse source 
Like:
  Error return value of alg.Write is not checked (from errcheck)

Actually even though the hash.Hash implements an io.Writer interface (that
return meaningful things on .Write()) it has this comment in its
documentation:

// Write (via the embedded io.Writer interface) adds more data to the running hash.
// It never returns an error.

so it should be OK to ignore return results here.
