Btrfs: fix hole check in log_one_extent
I added an assert to make sure we were looking up aligned offsets for csums and
I tripped it when running xfstests. This is because log_one_extent was checking
if block_start == 0 for a hole instead of EXTENT_MAP_HOLE. This worked out fine
in practice it seems, but it adds a lot of extra work that is uneeded. With
this fix I'm no longer tripping my assert. Thanks,
