[Replicant] [libsamsung-ipc] [PATCH 17/21] aries_gprs_get_iface: handle asprintf errors

[Denis 'GNUtoo' Carikli]

    Without that fix we have the following warning:
    ../../../samsung-ipc/devices/aries/aries.c:
    In function 'aries_gprs_get_iface':
    ../../../samsung-ipc/devices/aries/aries.c:826:9: warning:
    ignoring return value of 'asprintf' declared with attribute
    'warn_unused_result' [-Wunused-result]
      826 | asprintf(&iface, "%s%d", ARIES_GPRS_IFACE_PREFIX, cid - 1);
          | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
