scsi: core: Store owner from modules with scsi_register_driver()
Modules registering driver with scsi_driver_register() might forget to set
.owner field. The field is used by some of other kernel parts for
reference counting (try_module_get()), so it is expected that drivers will
set it.
Solve the problem by moving this task away from the drivers to the core
scsi code, just like we did for platform_driver in commit 9447057eaff8
("platform_device: use a macro instead of platform_driver_register").
