Hi Deven

the instruction above should be executed only if IPE LSM is
enabled. Otherwise, the kernel panics due to the illegal access
to the security blob of the task.

I see. I mistakenly assumed that failure in the LSM init would cause
a kernel panic (as the system is now booting without a potentially
required security component) as opposed to just disabling the LSM
and emitting a warning.

Easy fix for v8.

Thanks for pointing it out.
