Subject: [PATCH] [TCP] tcp_read_sock: Allow recv_actor() return return
 negative error value.

tcp_read_sock() currently assumes that the recv_actor() only returns
number of bytes copied. For network splice receive, we may have to
return an error in some cases. So allow the actor to return a negative
error value.
