Fix socket option {linger, {true, 0}} to abort TCP connections
Up until now, if {linger, {true, 0}} is set on the socket and there is
data in the port driver queue, the connection is not aborted until
the port queue is empty and close() is called on the underlying file
descriptor. This bug allows an idle TCP client to prevent a server
from terminating the connection and freeing resources. This patch
fixes the problem by discarding the port queue if the socket is closed
when {linger, {true, 0}} is set.
