target: Move task tag into struct se_cmd + support 64-bit tags
Simplify target core and target drivers by storing the task tag a.k.a. command identifier inside struct se_cmd. For several transports (e.g. SRP) tags are 64 bits wide. Hence add support for 64-bit tags. (Fix core_tmr_abort_task conversion spec warnings - nab) (Fix up usb-gadget to use 16-bit tags - HCH + bart) Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Andy Grover <agrover@redhat.com> Cc: Sagi Grimberg <sagig@mellanox.com> Cc: <qla2xxx-upstream@qlogic.com> Cc: Felipe Balbi <balbi@ti.com> Cc: Michael S.
