btf: fix type id in BTF_KIND_FUNC struct data.

This patch corrects the addition of +1 on the type id, which originally
was done in the wrong location and led to func_dtd->dtd_type for
BTF_KIND_FUNC struct data to contain the type id of the previous entry.

gcc/ChangeLog:

	* btfout.cc (btf_collect_dataset): Corrects BTF type id.
