isaacs 2106ef000c net: Provide better error when writing after FIN
The stock writable stream "write after end" message is overly vague, if
you have clearly not called end() yourself yet.

When we receive a FIN from the other side, and call destroySoon() as a
result, then generate an EPIPE error (which is what would happen if you
did actually write to the socket), with a message explaining what
actually happened.
