target: pass sense_reason as a return value
Pass the sense reason as an explicit return value from the I/O submission path instead of storing it in struct se_cmd and using negative return values. This cleans up a lot of the code pathes, and with the sparse annotations for the new sense_reason_t type allows for much better error checking. (nab: Convert spc_emulate_modesense + spc_emulate_modeselect to use sense_reason_t with Roland's MODE SELECT changes) Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: Roland Dreier <roland@purestorage.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
