[PATCH 1/4] btrfs-progs: Remove non-exist csum size.

[Qu Wenruo <quwenruo@cn.fujitsu.com>]

Current btrfs only support CRC32 as checksum algorithm.
But in btrfs_csum_sizes array, we have an extra 0 at tail, causing
csum_type 1 can still be considered as supported csum type.

Fix it by removing the tailing 0.
