perf annotate: Fix multiple memory and file descriptor leaks
Store SYMBOL_ANNOTATE_ERRNO__BPF_MISSING_BTF in variable *ret*, instead
of returning in the middle of the function and leaking multiple
resources: prog_linfo, btf, s and bfdf.
Addresses-Coverity-ID: 1454832 ("Structurally dead code")
Fixes: 11aad897f6d1 ("perf annotate: Don't return -1 for error when doing BPF disassembly")
