sparc64: Fix ITLB handler of null page
[ Upstream commit 1c2696cdaad84580545a2e9c0879ff597880b1a9 ]
1)Use kvmap_itlb_longpath instead of kvmap_dtlb_longpath.
2)Handle page #0 only, don't handle page #1: bleu -> blu
(KERNBASE is 0x400000, so #1 does not exist too. But everything
is possible in the future. Fix to not to have problems later.)
3)Remove unused kvmap_itlb_nonlinear.
