Matthew Wilcox (Oracle) c3bf90c6aa sparc: fix handling of page table constructor failure
[ Upstream commit 06517c9a33 ]

The page has just been allocated, so its refcount is 1.  free_unref_page()
is for use on pages which have a zero refcount.  Use __free_page() like
the other implementations of pte_alloc_one().
