[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).
