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.
