Fix goroutine lead in install action

a case in RunWithContex()
RunWithContex() {
go i.performInstall // running for a longer time
go i handleContex // return from ctx.Done() and send message to rchan, but performInstall is always running
result := < -rChan //read message
}

the message in rchan will be received in RunWithContex(), and RunWithContex() returns soon.
so, this case lead to goroutine performInstall leak
