bpftool: Fix bug for long instructions in program CFG dumps
[ Upstream commit 67cf52cdb6c8fa6365d29106555dacf95c9fd374 ]
When dumping the control flow graphs for programs using the 16-byte long
load instruction, we need to skip the second part of this instruction
when looking for the next instruction to process. Otherwise, we end up
printing "BUG_ld_00" from the kernel disassembler in the CFG.
