wwan: T9350: properly disconnect "disconnect interface wwanN"

Two things kept an operator disconnect from taking effect.

vyos-netlinkd re-dials every configured WWAN interface that has lost its
session. It cannot tell a session lost to RF signal loss from one that was
taken down on purpose, so the disconnect was undone on the next reconcile
pass, at most 30 seconds later:

  $ disconnect interface wwan0
  08:53:33 t+10s state=registered
  08:53:43 t+20s state=registered
  08:53:53 t+30s state=connected     <- re-dialled
  08:54:03 t+40s state=connected

  vyos-netlinkd: WWAN interface wwan0 is not connected, re-dialling...
  vyos-netlinkd: Re-dialled WWAN interface wwan0

Record the intent instead of inferring it from the session state. op-mode
"disconnect" drops a marker in /run/vyos-wwan, which _reconcile_wwan() honours
and "connect" removes again. conf_mode removes it too, so a commit keeps
re-asserting the configured state - the marker only survives for as long as
nobody says otherwise, and never across a reboot.
