This moves core_alua_check_nonop_delay to transport_handle_cdb_direct so the iSCSI target driver doesn't have to call as many core functions directly. This patchset will eventually merge transport_handle_cdb_direct and target_submit so iSCSI and the other drivers call a common function. It will also be helpful with the next patches which allow the iSCSI target to defer command submission to the lio submission workqueue, because we will have a common submission function for that which will be based on transport_handle_cdb_direct/target_submit.
