PATCH 1/1 btrfs: use IS_ALIGNED() for assertion in btrfs_lookup_csums_range() for simplicity

From: Satoru Takeuchi <[email protected]>

btrfs_lookup_csums_range() uses ALIGN() to check if "start" and "end + 1" are aligned to "root->sectorsize". It's better to replace these with IS_ALIGNED() for simplicity.
