btrfs: scrub: remove kmap/kunmap of pages All pages that scrub uses in the scrub_block::pagev array are allocated with GFP_KERNEL and never part of any mapping, so kmap is not necessary, we only need to know the page address. In scrub_write_page_to_dev_replace we don't even need to call flush_dcache_page because of the same reason as above. Signed-off-by: David Sterba <dsterba@suse.com>
