beam_lib: Handle rare race in the crypto key server functionality
In rare circumstances, there can be a race when the crypto key server is started by beam_lib:crypto_key_fun/1 shortly after stopping it using beam_lib:clear_crypto_key_fun/0. The race occurs because the crypto key server first sends back the reply to the calling process, then terminates. (The race is probably more likely to happen on CPUs with hyper threading.)
