ipa_ccm_idtag_parse*: Fix reported length value
IPA CCM is using a somewhat weird TLV encoding scheme:
* 16bit length (of tag and value)
* 8bit tag
* value
Our existing code mapping the CCM to 'struct tlv_parse' used the plain
length value without accounting for the one-byte tag.
This patch ensures we only report the length of the "value" part,
excluding the tag.
