net: wwan: core: Return poll error in case of port removaltelit-5.12
Ensure that the poll system call returns error flags when port is
removed, allowing user side to properly fail, without trying read
or write. Port removal leads to nullified port operations, add a
is_port_connected() helper to safely check the status.
