Fix following build warnings:

init/initramfs.c: In function 'populate_rootfs_early':
init/initramfs.c:629:7: warning: passing argument 1 of 'async_schedule_domain' from incompatible pointer type [enabled by default]
include/linux/async.h:20:23: note: expected 'void (*)(void *, async_cookie_t)' but argument is of type 'void (*)(void)'
init/initramfs.c:631:1: warning: no return statement in function returning non-void [-Wreturn-type]
init/initramfs.c: In function 'populate_rootfs':
init/initramfs.c:636:7: warning: passing argument 1 of 'async_schedule_domain' from incompatible pointer type [enabled by default]

Patch applies from Natty to Quantal.
It's just build warnings, but if desired I can open a bug and do the formal SRU.
