What this PR does / why we need it (en: English/zh: Chinese):
en: There are a few cases that lastArgs.cap == 0 but lastArg.len == MAX_INT when calling variadic functions (arm64). Currently we have no idea how it happens. In that case we assume that lastArgs.len should less than lastArg.cap
zh: 在一些极少情况下mock可变长参数的函数，调用时最后的变长参数slice的len会变得很大，但是cap为0。目前还不清楚为什么slice的len被踩坏了，这里先做一个校验，如果len>cap的话按照cap长度调用mock函数
