sparc64: Fix ITLB handler of null page
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.
