Bart Van Assche 140c5af41c scstadmin: Set hardware target attributes correctly 
For target drivers that support creating targets, e.g. the Emulex
FC driver, it is possible that a target attribute is both writable
for existing (hardware) targets and that it has to be specified
when creating a (virtual) target. Make sure that scstadmin sets
these attributes for existing (hardware) targets when restoring a
configuration.

Vladislav Bolkhovitin c66294d36f Avoid that unloading SCST hangs when using bcache 
Although it seems to be bcache problem, remove the
flush_scheduled_work() call because it is not necessary. Call
cancel_delayed_work_sync() after unregistration from sysfs just in case
a sysfs attribute would ever be added that allows to trigger pool
purging directly.
