	syssrc/sys/arch/sparc64/sparc64: pmap.c

Log Message:
add back some cache flushes that are actually necessary.
any time we remove all access to a given virtual page,
we must invalidate the (write-through) L1 dcache.
pmap_remove() still had it, but pmap_kremove(), pmap_clear_reference()
and pmap_page_protect(VM_PROT_NONE) didn't and needed it.
fixes PR 18040.
