bpf: Call the missed kfree() when there is no special field in btf
Call the missed kfree() in btf_parse_struct_metas() when there is no
special field in btf, otherwise will get the following kmemleak report:
unreferenced object 0xffff888101033620 (size 8):
comm "test_progs", pid 604, jiffies 4295127011
......
