target: add struct spc_ops + initial ->execute_rw pointer usage
Remove the execute_cmd method in struct se_subsystem_api, and always use the one directly in struct se_cmd. To make life simpler for SBC virtual backends a struct spc_ops that is passed to sbc_parse_cmd is added. For now it only contains an execute_rw member, but more will follow with the subsequent commits. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
