detect: don't consider smsgs for no inspect flag

When the PKT_NOPAYLOAD_INSPECTION flag is set, don't apply it to smsgs.
This way we can still inspect the outstanding smsgs.

The PKT_NOPAYLOAD_INSPECTION is set for encrypted traffic, and is combined
with disabling stream reassembly. So we only inspect the smsgs up to the
point of the disable detection point.
