Add call to lzo's lzo1x_decompress_safe() and rename source length parameter from 'lenp' to 'src_len'.
U-Boot's LZO sources may still have some unsolved issues that could make the decompression crash when dealing with fragmented files, so those should be avoided. The "-no-fragments" option can be passed to mksquashfs.
