H A Ddecompress_unlz4.cdiff 2a1d689c9ba42a6066540fb221b6ecbd6298b728 Fri Jan 24 00:56:20 CET 2014 Jan Beulich <JBeulich@suse.com> lib/decompress_unlz4.c: always set an error return code on failures

"ret", being set to -1 early on, gets cleared by the first invocation of
lz4_decompress()/lz4_decompress_unknownoutputsize(), and hence subsequent
failures wouldn't be noticed by the caller without setting it back to -1
right after those calls.
