c8ed668593 selftests/bpf: fix lots of silly mistakes pointed out by compiler 
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.

5e0b0a4c52 selftests/bpf: Test tail call counting with bpf2bpf and data on stack 
Cover the case when tail call count needs to be passed from BPF function to
BPF function, and the caller has data on stack. Specifically when the size
of data allocated on BPF stack is not a multiple on 8.
