[PATCH] examples/pipeline: fix build with some compilers

[Ali Alnubani]

Fixes the following build failure with gcc 5.4.0 because
of uninitialized variables:

[..]
examples/pipeline/cli.c:1801:10: error: 'idx' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
[..]
examples/pipeline/cli.c:1916:10: error: 'idx' may be used
  uninitialized in this function [-Werror=maybe-uninitialized]
[..]

Fixes: 83f58a7b7b0a ("examples/pipeline: add commands for direct registers")
