perf/core: Preserve AUX buffer allocation failure result
A recent overhaul sets the return value to 0 unconditionally after the
allocations, which causes reference count leaks and corrupts the user->vm
accounting.
Preserve the AUX buffer allocation failure return value, so that the
subsequent code works correctly.
