scsi: cxgb3i: Fix some leaks in init_act_open()
There wasn't any clean up done if cxgb3_alloc_atid() failed and also the original code didn't release "csk->l2t". Link: https://lore.kernel.org/r/20200521121221.GA247492@mwanda Fixes: 6f7efaabefeb ("[SCSI] cxgb3i: change cxgb3i to use libcxgbi") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Martin K.
