Subject: [PATCH] dlm: remove redundant variable assignments

From: Xue Ying <ying.xue@...driver.com>

Once the tcp_create_listen_sock() is returned successfully, we
will invoke add_sock() immediately. In add_sock(), the 'con'
variable is assigned to 'sk_user_data', meanwhile, the 'sock' is
also set to 'con->sock'. So it's unnecessary to do the same thing
in tcp_create_listen_sock().
