random: remove unused get_random_var_wait functions 



None of these functions are used, so remove them.

This renders the two bugs moot:

- get_random_u64_wait() used the wrong pointer type, making it provide
  only 32 bits.

- The '#undef' directive used the wrong identifier, leaving the helper
  macro defined.
