Decompressors: fix callback-to-callback mode in decompress_unlzo.c
Callback-to-callback decompression mode is used for initrd (not
initramfs). The LZO wrapper is broken for this use case for two reasons:
- The argument validation is needlessly too strict by
requiring that "posp" is non-NULL when "fill" is non-NULL.
- The buffer handling code didn't work at all for this
use case.
I tested with LZO-compressed kernel, initramfs, initrd, and corrupt
(truncated) initramfs and initrd images.
