Squashfs: fix f_pos check in get_dir_index_using_offset
One off error in the f_pos check. If f_pos is 3 or less don't bother reading the index because we're at the start of the directory, and we obviously already know where that is on disk. This eliminates an unnecessary read. Signed-off-by: Phillip Lougher <phillip@squashfs.org.uk>
