Revert "SUNRPC: Ensure we close the socket on EPIPE errors too..."

This reverts commit a9ea97e0dfbb0e3e765e4b8791b3e3b746f680a5.
Now that we clear the connected flag when entering TCP_CLOSE_WAIT,
the deadlock described in this commit is no longer possible.
Instead, the resulting call to xs_tcp_shutdown() can interfere
with pending reconnection attempts.
