[PATCH v2 3/8] module: Fix adding module to list after layout

[David Dgien]

During load_module(), the 'this_module' section is relocated, but the
pointer to the module struct isn't updated to account account for the
move. Do so before adding the module to the module_list.

As a side effect of properly pointing to the relocated module struct, we
no longer need to manually search for and fixup the init_module symbol,
so remove that code.
