btrfs: use aligned range for locking in reflink

Browse source

In btrfs_extent_same_range() and btrfs_clone_files(), the range passed
into btrfs_lock_extent() is not aligned at its end, because we can
reflink until the EOF, which may not be block aligned.

Although this is not a big deal, for the sake of consistency, and to
prepare for the upcoming stricter alignment check, pass an aligned range
end to btrfs_lock_extent() and btrfs_unlock_extent().
