Anoob Soman 3491857f42 scsi: libiscsi: Fix race between iscsi_xmit_task and iscsi_complete_task 
[ Upstream commit 79edd00dc6 ]

When a target sends Check Condition, whilst initiator is busy xmiting
re-queued data, could lead to race between iscsi_complete_task() and
iscsi_xmit_task() and eventually crashing with the following kernel
backtrace.

Commit 6f8830f5bb ("scsi: libiscsi: add lock around task lists to fix
list corruption regression") introduced "taskqueuelock" to fix list
corruption during the race, but this wasn't enough.

Re-setting of conn->task to NULL, could race with iscsi_xmit_task().
iscsi_complete_task()
{
    ....
    if (conn->task == task)
        conn->task = NULL;
}

conn->task in iscsi_xmit_task() could be NULL and so will be task.
__iscsi_get_task(task) will crash (NullPtr de-ref), trying to access
refcount.

iscsi_xmit_task()
{
    struct iscsi_task *task = conn->task;

    __iscsi_get_task(task);
}

This commit will take extra conn->session->back_lock in iscsi_xmit_task()
to ensure iscsi_xmit_task() waits for iscsi_complete_task(), if
iscsi_complete_task() wins the race.  If iscsi_xmit_task() wins the race,
iscsi_xmit_task() increments task->refcount
(__iscsi_get_task) ensuring iscsi_complete_task() will not iscsi_free_task().
