Subject: [PATCH] Revert "uapi/linux/keyctl.h: don't use C++ reserved keyword as a struct member name"

This changes UAPI, breaking iwd and libell:

  ell/key.c: In function 'kernel_dh_compute':
  ell/key.c:205:38: error: 'struct keyctl_dh_params' has no member named 'private'; did you mean 'dh_private'?
    struct keyctl_dh_params params = { .private = private,
                                        ^~~~~~~
                                        dh_private

This reverts commit 8a2336e549d385bb0b46880435b411df8d8200e8.
