Make libpayload alloc() memory pointers volatile

gcc4.6.2 was optimizing the libpayload alloc() function and failing to
    reload a pointer after the memory had been manipulated by a pointer in
    the inlined function setup(). Change the pointer type to volatile
    and now pass it to the setup() function. Also clean up the
    declaration so that it isn't cast a bunch times in the function.
