[Replicant] [libsamsung-ipc] [PATCH 19/21] tools: nv_data-imei: Fix unused result warning

[Denis 'GNUtoo' Carikli]

Without that fix, when running the following commands:
    $ cd tools
    $ makepkg
we have:
../../../tools/nv_data-imei.c: In function ‘write_imei’:
../../../tools/nv_data-imei.c:769:9: warning:
ignoring return value of ‘asprintf’
declared with attribute ‘warn_unused_result’ [-Wunused-result]
  769 |         asprintf(&md5_path, "%s.md5", nv_data_path);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
