ext4fs: use EXT2_BLOCK_SIZE instead of fs->blksz
Using fs->blksz in ext4fs_get_extent_block() is not correct since fs->blksz is not initialized on the read path. Use EXT2_BLOCK_SIZE() instead which will produce the desired output. Signed-off-by: Ionut Nicu <ioan.nicu.ext@nsn.com> Signed-off-by: Mathias Rulf <mathias.rulf@nsn.com>
