module: move check_modinfo() early to early_mod_check()

This moves check_modinfo() to early_mod_check(). This
doesn't make any functional changes either, as check_modinfo()
was the first call on layout_and_allocate(), so we're just
moving it back one routine and at the end.

This let's us keep separate the checkers from the allocator.
