Shung-Hsi Yu 345652866a bpf: fix overflow check in adjust_jmp_off() 
[ Upstream commit 4a04b4f0de59dd5c621e78f15803ee0b0544eeb8 ]

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.")
