2023-03-10selftests/bpf: fix lots of silly mistakes pointed out by compilerAndrii Nakryiko1-0/+4
Once we enable -Wall for BPF sources, compiler will complain about lots of unused variables, variables that are set but never read, etc. Fix all these issues first before enabling -Wall in Makefile.

test_global_func[12] - check 512 stack limit. test_global_func[34] - check 8 frame call chain limit. test_global_func5 - check that non-ctx pointer cannot be passed into a function that expects context. test_global_func6 - check that ctx pointer is unmodified. test_global_func7 - check that global function returns scalar.
