[PATCH 4.9/scsi-fixes] libcxgbi: fix incorrect DDP resource cleanup

[Varun Prakash <varun@chelsio.com>]

Before calling task_release_itt() task data is memset
to zero because of which DDP context information is lost
resulting in incorrect DDP resource cleanup, to fix
this call task_release_itt() before memset.
