Ian Rogers 4924b1f7c4 perf bpf: Avoid memory leak from perf_env__insert_btf() 
perf_env__insert_btf() doesn't insert if a duplicate BTF id is
encountered and this causes a memory leak. Modify the function to return
a success/error value and then free the memory if insertion didn't
happen.

v2. Adds a return -1 when the insertion error occurs in
    perf_env__fetch_btf. This doesn't affect anything as the result is
    never checked.

Fixes: 3792cb2ff4 ("perf bpf: Save BTF in a rbtree in perf_env")
