This in reality might not work for multi_*(). Because if a username/
password prompt just shows up, what transfer is it part of?

For this change, and possibly others we might want to thing about
libssh2_userauth_keyboard_interactive_ex2() where this one has the
extra private pointer. libssh2_userauth_keyboard_interactive_ex()
would just call libssh2_userauth_keyboard_interactive_ex2() with a
null for the private pointer.
