libext2fs: correctly subtract xattr blocks on bigalloc filesystems ext2fs_inode_data_blocks2() calculates an inode's data block count by subtracting the external xattr block, if any, from the total blocks. But on bigalloc filesystems, the xattr "block" is actually a whole cluster, so ext2fs_inode_data_blocks2() would return a too-large value. It seems this could have caused several different problems, but the one I encountered was that xfstest generic/399 failed in the "bigalloc" config because e2fsck incorrectly considered a symlink on the filesystem to be corrupted at the end of the test. This happened because e2fsck incorrectly calculated a nonzero data block count for a "fast" symlink with an external xattr block and therefore treated it as a "slow" symlink, which failed validation. Fix this by updating ext2fs_inode_data_blocks2() to subtract the cluster size rather than the block size.
