detect: update packet action on protocol change

Ticket: #6305

When running FlowWorkerStreamTCPUpdate, one of the dequeued packet
may set the flow action to drop, without updating the not-pseudo
packet action, as is done usually with a previous call to
FlowHandlePacketUpdate

(cherry picked from commit 4c4f7ff1a2324bff9e4e09dd8354878b2455ac34)
