[PATCH] uninline init_waitqueue_head()

allyesconfig vmlinux size delta:

  text            data    bss     dec          filename
  20736884        6073834 3075176 29885894     vmlinux.before
  20721009        6073966 3075176 29870151     vmlinux.after

~18 bytes per callsite, 15K of text size (~0.1%) saved.

(as an added bonus this also removes a lockdep annotation.)
