Btrfs: add an assert to btrfs_lookup_csums_range for alignment
I was hitting weird issues when trying to remove hole extents and it turned out it was because I was sending non-aligned offsets down to btrfs_lookup_csums_range. So add an assert for this in case somebody trips over this in the future. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
