tlv.h: Fix TLVP_PRESENT returning a pointer instead of a boolean

I was warned by gcc about comparing a pointer with an integer when using TLVP_PRESENT with something like: bool expect = ...; if (expect != TLV_PRESENT(...))

That's indeed dangerous because TLV_PRESENT is considered to return a boolean, as opposite to TLV_VAL.
