bpf: fix overflow check in adjust_jmp_off()
adjust_jmp_off() incorrectly used the insn->imm field for all overflow check,
which is incorrect as that should only be done or the BPF_JMP32 | BPF_JA case,
not the general jump instruction case. Fix it by using insn->off for overflow
check in the general case.
Fixes: 5337ac4c9b80 ("bpf: Fix the corner case with may_goto and jump to the 1st insn.")
