caffe_rng_gaussian - remove unnecessary check

[stevenryoung]

mu does not need to be less than sigma.

Example case where this causes problem.

44 layer { 45 name: "fake_data" 46 type: "DummyData" 47 top: "fake_data" 48 include { 49 phase: TRAIN 50 } 51 dummy_data_param { 52 data_filler { 53 type: "gaussian" 54 mean: 1.0 55 std: 0.01 56 } 57 shape { 58 dim: 16 59 dim: 2 60 dim: 100 61 dim: 80 62 } 63 } 64 }

It looks like the only check that failed was a build configuration that timed out while compiling.
