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,
