lib: fix the use of LZO to decompress initramfs images
This patch fixes 2 issues with the LZO decompressor:
- It doesn't handle the case where a block isn't compressed at all. In
this case, calling lzo1x_decompress_safe will fail, so we need to just
use memcpy() instead (the upstream LZO code does something similar)
- Since commit 54291362d2a5738e1b0495df2abcb9e6b0563a3f ("initramfs: add
missing decompressor error check") , the decompressor return code is
checked in the init/initramfs.c The LZO decompressor didn't return the
expected value, causing the initramfs code to falsely believe a
decompression error occured
