[PATCH] LSM: SafeSetID: Mark safesetid_initialized as __initdata

[Micah Morton]

Thanks for the patch. Looks right, since that variable is only used in
safesetid_security_init() and safesetid_init_securityfs(), which are
both marked __init. I can merge it to the safesetid-next branch today
and send the patch through my tree during the 5.14 merge window.
