[PATCH] Fix not waiting for POLLERR when disconnecting SCO

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.dentz-von@nokia.com>

To make sure the SCO link is really disconnected we should wait for
POLLERR since POLLHUP does not necessarily means the link is
completely disconnected just that no further data can be sent/received.

Note that this depend on a fix of SCO socket shutdown in kernel to wait
for disconnect confimation to then kill/destroy the socket indicating
the err/reason using POLLERR.
