net: bpf_jit: fix an off-one bug in x86_64 cond jump target
[ Upstream commit a03ffcf873fe0f2565386ca8ef832144c42e67fa ]
x86 jump instruction size is 2 or 5 bytes (near/long jump), not 2 or 6
bytes.
In case a conditional jump is followed by a long jump, conditional jump
target is one byte past the start of target instruction.
