kho: free chunks using free_page() instead of kfree() 

Before commit fa759cd7 ("kho: allocate metadata directly from the
buddy allocator"), the chunks were allocated from the slab allocator using
kzalloc().  Those were rightly freed using kfree().

When the commit switched to using the buddy allocator directly, it missed
updating kho_mem_ser_free() to use free_page() instead of kfree().
