Decompressors: check for write errors in decompress_unlzma.c
The return value of wr->flush() is not checked in write_byte(). This
means that the decompressor won't stop even if the caller doesn't want
more data. This can happen e.g. with corrupt LZMA-compressed initramfs.
Returning the error quickly allows the user to see the error message
quicker.
There is a similar missing check for wr.flush() near the end of unlzma().
