[spp] [PATCH 2/3] shared/sec: rename func to get type idx for cls

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

This update is to rename function for parsing getting index of type of
classifier `decode_classifier_type_value()` to `parse_cls_type()`,
and refactoring.
