binder: fix pointer cast warning
binder_uintptr_t is not the same as uintptr_t, so converting it into a
pointer requires a second cast:
drivers/android/binder.c: In function 'binder_translate_fd_array':
drivers/android/binder.c:2511:28: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
2511 | sender_ufda_base = (void __user *)sender_uparent->buffer + fda->parent_offset;
| ^
Fixes: 656e01f3ab54 ("binder: read pre-translated fds from sender buffer")
