Refactor CTL datamove KPI.
- Make frontends call unified CTL core method ctl_datamove_done() to report move completion. It allows to reduce code duplication in differerent backends by accounting DMA time in common code. - Add to ctl_datamove_done() and be_move_done() callback samethr argument, reporting whether the callback is called in the same context as ctl_datamove(). It allows for some cases like iSCSI write with immediate data or camsim frontend write save one context switch, since we know that the context is sleepable. - Remove data_move_done() methods from struct ctl_backend_driver, unused since forever. MFC after: 1 month
