mm/mm_init.c: remove the outdated code comment above deferred_grow_zone()

The noinline attribute has been taken off in commit 9420f89db2dd ("mm:
move most of core MM initialization to mm/mm_init.c").  So remove the
unneeded code comment above deferred_grow_zone().

And also remove the unneeded bracket in deferred_init_pages().
