examples/pipeline: fix build

This patch fixes the following build failures seen on Ubuntu 16.04
with gcc 5.4.0 because of uninitialized variables:
...
examples/pipeline/cli.c:1559:11: error: 'weight_val' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
...
examples/pipeline/cli.c:1545:13: error: 'member_id_val' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
...
examples/pipeline/cli.c:1538:12: error: 'group_id_val' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
...
examples/pipeline/cli.c:2189:2: error: 'idx1' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
...
examples/pipeline/cli.c:2179:43: error: 'idx0' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
...
examples/pipeline/cli.c:2265:2: error: 'idx1' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
...
examples/pipeline/cli.c:2248:43: error: 'idx0' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
...
examples/pipeline/cli.c:2358:2: error: 'idx1' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
...
examples/pipeline/cli.c:2325:43: error: 'idx0' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
