kernel - Add missing vm_page_wakeup()
* Fix a long-standing issue where a VM page is improperly left PG_BUSY
when vm_page_try_to_cache() races the Modified bit in underlying PTEs.
* This could only occur during periods of severe memory pressure and
would typically lead to a program getting stuck in "pgtblk".
