Subject: Decompressors: fix header validation in decompress_unlzma.c
From: Lasse Collin <lasse.collin@xxxxxxxxxxx>
Validation of header.pos calls error() but doesn't make the function
return to indicate an error to the caller. Instead the decoding is
attempted with invalid header.pos. This fixes it.
