p2p: fix re-launch wpa_supplicant unintentionally

When supplicant death handling runs prior to p2p interface removing
handler, getSupplicantMockableV1_1 would get NoSuchElement exception
by calling ISupplicant.getSupplicant() directly due to
the nonexistence of supplicant daemon.
In the meantime, call ISupplicant.getService() would also trigger lazy
HAL initialization to launch supplicant daemon unintentionally.
