[PATCH v2 13/23] qmi: call-settings: Drop use of qmi_service_create_shared

[Denis Kenzior <denkenz@gmail.com>]

While here, drop 'sups_ind_id' member.  Explicitly unregistering from a
an indication is not required.  All indication registrations will be
automatically dropped when the service handle is freed using
qmi_service_free()
