The kernel keeps two different pointers for 32-bit and 64-bit futex
lists: robust_list and compat_robust_list in task_struct.
So, dump compat_robust_list for ia32 tasks.

Note: this means that one can set *both* compat_robust_list and
robust_list pointers by using as we're here 32-bit and 64-bit syscalls.
That's one of mixed-bitness application questions.
For simplification (and omitting more syscalls), we dump here only
one of the pointers.
