The use of kmap() is being deprecated in favor of kmap_local_page() where
it is feasible. With kmap_local_page(), the mapping is per thread, CPU
local and not globally visible.
load_and_flush_by_kmap() is a function where the use of kmap_local_page()
in place of kmap() is correctly suited.
Convert load_and_flush_by_kmap() from kmap() to kmap_local_page().
