  lib-smtp: server: Fix panic when io_remove() is called too late

With submission-login the conn_disconnect() callback ends up in
login-common's client_disconnect(), which closes the file descriptor.
The io_remove() was done afterwards, which caused a crash:

submission-login: Panic: epoll_ctl(del, 18) failed: Bad file descriptor
