    Store errors from TLS write and handshake in the tls_error field.
    
    Previously, we would only update this field when the error happened
    during a read.
    
    This will improves our reporting for our bootstrap status, and help
    to address #32622.  The problem is not completely solved by this
    patch, however: too many errors are still lumped into "MISC".
