Subject: [PATCH] Make the AES availability cache actually cache things!

Ahem. I went to all the effort of setting up a wrapper function that
would store the result of the first call to aes_hw_available(), and
managed to forget to make it set the flag that said it _had_ stored
the result. So the underlying query function was being called every
time.
