src/msg/dpdk: reserve funcs capacity to avoid reallocation

Browse Source 
When a new vector is added larger than then current vector capacity,
it reallocates space. lamda function accesses the previous adress will
cause a segment fault. Therefore, reserve sufficient funcs space to
avoid reallocation.
