Mike Christie f457a46f17 [SCSI] iscsi_ibft, be2iscsi, iscsi_boot: fix boot kobj data lifetime management
be2iscsi passes the boot functions its phba object which is
allocated in the shost, but iscsi_ibft passes in a object
allocated for each item to display. The problem is that
iscsi_boot_sysfs was managing the lifetime of the object
passed in and doing a kfree on release. This causes a double
free for be2iscsi which frees the shost in its pci_remove.

This patch fixes the problem by adding a release callback
which the drivers can call kfree or a put() type of function
(needed for be2iscsi which will do a get/put on the shost).

Mike Christie 9d04516310 [SCSI] iscsi_boot_sysfs: have this module check for null on destruction
This moves the check for NULL boot_sets to the iscsi_boot_sysfs
module instead of having the drivers do it.

Mike Christie aab7a8fd19 [SCSI] iscsi boot: mv iscsi_boot_sysfs to drivers/scsi
iscsi_boot_sysfs does not depend on firmware. Any iscsi driver
can use it. This patch moves iscsi_boot_sysfs to the scsi
dir, so that it can be used on any arch with any driver.
