[PATCH v7 for-next 2/8] livepatch: Call klp_init_patch_early() earlier

[Yafang Shao <laoar.shao@gmail.com>]

Invoke klp_init_patch_early() during early initialization to avoid
mixing for_each_() and for_each_*_static() variants later in the code.

No functional change. This prepares the code for an upcoming patch.
