Randall Stewart 02cffbc250 tcp: Incorrect KASSERT causes a panic in rack
Skyzall found an interesting panic in rack. When a SYN and FIN are
both sent together a KASSERT gets tripped where it is validating that
a mbuf pointer is in the sendmap. But a SYN and FIN often will not
have a mbuf pointer. So the fix is two fold a) make sure that the
SYN and FIN split the right way when cloning an RSM SYN on left
edge and FIN on right. And also make sure the KASSERT properly
accounts for the case that we have a SYN or FIN so we don't
panic.
