cbfstool: Propogate compression errors back to the caller.

Browse Source 
When compression fails for whatever reason, the caller should know about it
rather than blindly assuming it worked correctly. That can prevent half
compressed data from ending up in the image.

This is currently happening for a segment of depthcharge which is triggering
a failure in LZMA. The size of the "compressed" data is never set and is
recorded as zero, and that segment effectively isn't loaded during boot.
