sparc: fix handling of page table constructor failure
[ Upstream commit 06517c9a336f4c20f2064611bf4b1e7881a95fe1 ]
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().
