There is no reason to do i+dcache writeback and invalidate when changing

especially bad to do so using a cache operation that isn't coherent on

iscsi.ko unloadable, and building ctl.ko without iscsi.ko (using
MODULES_OVERRIDE) results in ctl.ko that is unloadable, due to missing
symbols that would be resolved to iscsi.ko. And since the symbols
