lzma: Return correct amount of decompressed bytes

The LZMA functions are supposed to return the decompressed size, but
    what they actually return is just an unaltered field from the LZMA
    header that is *supposed* to contain the decompressed size. Apparently
    some encoders just overshoot that for no good reason. This patch changes
    the code such that the actual amount of decompressed bytes is returned.

BRANCH=smaug
    BUG=None
    TEST=Printed output bytes when decompressing kernels with LZMA in
    depthcharge, noted that amounts now make sense.
