btrfs: fix btrfs_extend_item() comment
The size parameter to btrfs_extend_item() is the number of bytes to add to the item, not the size of the item after the operation (like it is for btrfs_truncate_item(), there the size parameter is not the number of bytes to take away, but the total size of the item after truncation). Fix it in the comment. Signed-off-by: Stefan Behrens <sbehrens@giantdisaster.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
