QUIC: ngx_quic_buffer_t use-after-free protection. Previously the last chain field of ngx_quic_buffer_t could still reference freed chains and buffers after calling ngx_quic_free_buffer(). While normally an ngx_quic_buffer_t object should not be used after freeing, resetting last_chain field would prevent a potential use-after-free.
