btrfs: move kmapping out of btrfs_check_sector_csum()

Browse source

Move kmapping the page out of btrfs_check_sector_csum().

This allows using bvec_kmap_local() where suitable and reduces the number
of kmap*() calls in the raid56 code.

This also means btrfs_check_sector_csum() will only accept a properly
kmapped address.
