kernel: globalize lookup_or_create_module_kobject()

[ Upstream commit 7c76c813 ]

lookup_or_create_module_kobject() is marked as static and __init,
to make it global drop static keyword.
Since this function can be called from non-init code, use __modinit
instead of __init, __modinit marker will make it __init if
CONFIG_MODULES is not defined.
