lib/crc: Drop inline from all *_mod_init_arch() functions

Drop 'inline' from all the *_mod_init_arch() functions so that the
compiler will warn about any bugs where they are unused due to not being
wired up properly.  (There are no such bugs currently, so this just
establishes a more robust convention for the future.  Of course, these
functions also tend to get inlined anyway, regardless of the keyword.)
