eloop/poll: Handle POLLER | POLLHUP in read logic

Without this, we can get into a tight loop because the
code in general doesn't add eloop exception handlers,
so socket reporting the POLLERR would never be read.

With this change, any socket with POLLERR or POLLHUP
asserted will be handled by the read logic.
