Fix the bug in regularizer matching (#23485)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/23485
In previous diff D16326492, the "regularizer" in dot processor is defined according to input regularizer options through the function "get_emb_weighting_reg" in processor_utils.py. The option matching is only valid in local test, but doesn't work in workflows. This bug causes the regularizer not added in actual models and has made previous trimmed lasso implementation useless.
An evidence is that before D16326492, a flow f126010621 has elastic regularizer added:

while after D16326492, the regularizer is gone in flow f127262007
