[PATCH] udevng: restore support for phonet modems

Commit 296347f8a4f1 ("udevng: Detect embedded qmi QRTR modems") introduced
a constraint that only rmnet_* modems are valid "net" subsystem devices, thus
breaking phonet modems, which are located in that subsystem as well.

    P: /devices/platform/68000000.ocp/48058000.ssi-controller/ssi0/port0/ssi-protocol/net/phonet0
    E: DEVPATH=/devices/platform/68000000.ocp/48058000.ssi-controller/ssi0/port0/ssi-protocol/net/phonet0
    E: INTERFACE=phonet0
    E: OFONO_DRIVER=n900
    E: OFONO_ISI_ADDRESS=108
    E: SUBSYSTEM=net

Fix the regression by specifically checking for phonet inside
check_net_device().
