[PATCH 07/14] qla2xxx: Convert to new submission API

target_submit_cmd is now only for simple drivers that do their
own sync during shutdown and do not use target_stop_session.

tcm_qla2xxx uses target_stop_session to sync session shutdown with lio
core, so we use target_init_cmd/target_submit_prep/target_submit, because
target_init_cmd will detect the target_stop_session call and return
an error.
