close agent socket after authentication

The problem here is that pubkey_prepare() was setting
authctxt.agent_fd, but it was then being clobbered by the subsequent
authctxt preparation in ssh_userauth2().

The fix moves the pubkey_prepare() call down to after the preparation
of authctxt is complete and also adds some cleanup of agent_fd after it
is closed.
