4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Maurizio Lombardi <mlombard@xxxxxxxxxx>

commit 84bd64993f916bcf86270c67686ecf4cea7b8933 upstream.

In beiscsi_setup_boot_info(), the boot_kset pointer should be set to
NULL in case of failure otherwise an invalid pointer dereference may
occur later.
