correct error messages for NULL packet_read_line()
The packet_read_line() function dies if it gets an unexpected EOF. It only returns NULL if we get a flush packet (or technically, a zero-length "0004" packet, but nobody is supposed to send those, and they are indistinguishable from a flush in this interface). Let's correct error messages which claim an unexpected EOF; it's really an unexpected flush packet. While we're here, let's also check "!line" instead of "!len" in the second case. The two events should always coincide, but checking "!line" makes it more obvious that we are not about to dereference NULL.
