In the unlikely event of the allocation failing, it is better to let
the machine boot with a not fully populated sysfs than to kill it with
this BUG_ON(). All callers are already prepared for
lookup_or_create_module_kobject() returning NULL.
This is also preparation for calling this function from non __init
code, where using BUG_ON for allocation failure handling is not
acceptable.
Since we are here, also start using IS_ENABLED instead of #ifdef
construct.
