[pve-devel] [PATCH access-control v2 3/3] authenticate_user: pass undef instead of empty $tfa_challenge to authenticate_2nd_new

[Dominik Csapak <d.csapak@proxmox.com>]

just above, we check & return if $tfa_challenge is set, so there is no
way that it would be set here. To make it clearer that it must be undef
here pass it as such.
