Fix networking tree iscsi_tcp.c mis-merge
The removal of the 'waitqueue_active()' test in commit d7d05548a6
("[SCSI] iscsi_tcp: fix relogin/shutdown hang") got incorrectly resolved
by David when he back-merged the main git tree into the networking tree
in commit 278554bd65 ("Merge branch 'master' of master.kernel.org:...").
There was a content conflict due to 'sock->sk->sk_sleep' being changed
into 'sk_sleep(sock->sk)' in the networking tree, but David didn't pick
up the iscsi change from the main tree.
