[PATCH v2 17/23] qmi: netreg: Drop use of qmi_service_create_shared

[Denis Kenzior <denkenz@gmail.com>]

While here, drop all indication registration id members.  Explicitly
unregistering from an indication is not required.  All indication
registrations will be automatically dropped when the service handle
is freed using qmi_service_free()
