net: Fix oops from tcp_collapse() when using splice()
commit baff42ab1494528907bf4d5870359e31711746ae upstream.
tcp_read_sock() can have a eat skbs without immediately advancing copied_seq.
This can cause a panic in tcp_collapse() if it is called as a result
of the recv_actor dropping the socket lock.
A userspace program that splices data from a socket to either another
socket or to a file can trigger this bug.
