Kees Cook 96a7b71c44 ubd: Use pointer-to-pointers for io_thread_req arrays 
Having an unbounded array for irq_req_buffer and io_req_buffer doesn't
provide any bounds safety, and confuses the needed allocation type,
which is returning a pointer to pointers. Instead of the implicit cast,
switch the variable types.
