accessorytest: Remove bad code

This code was calling 'free' on uninitialized stack memory.  However,
we never reached this code due to the while(1) loop, so we weren't
experiencing bad behavior.  Still, we remove this code to avoid
the temptation of copy/paste for someone in the future who might
leave this loop.
