Bart Van Assche dee7121e8c scsi: core: Change the return type of .eh_timed_out()
Commit 6600593cbd ("block: rename BLK_EH_NOT_HANDLED to BLK_EH_DONE")
made it impossible for .eh_timed_out() implementations to call
scsi_done() without causing a crash.

Restore support for SCSI timeout handlers to call scsi_done() as follows:

 * Change all .eh_timed_out() handlers as follows:

   - Change the return type into enum scsi_timeout_action.
   - Change BLK_EH_RESET_TIMER into SCSI_EH_RESET_TIMER.
   - Change BLK_EH_DONE into SCSI_EH_NOT_HANDLED.

 * In scsi_timeout(), convert the SCSI_EH_* values into BLK_EH_* values.
