Hi maintainer,

In /var/lib/iwd/<ssid>.8021x I have defined a corporate network,
without specifying my username or password. If I run `iwctl station
<interface> connect <ssid>`, I can succesfully enter my username.
After pressing return, iwctl asks for my password. However, I cannot
enter my password and iwctl does not respond to pressing return.
Terminating iwctl by pressing ^C terminates iwctl with a libc error
"free(): double free detected in tcache 2".

I have recompiled libell0 and iwd with AddressSanitizer and found
the error location. I have attached the output from AddressSanatizer.

There are no issues when I connect using the iwctl shell or when I
specify my username in the configuration file.
