lzma_lzma_decoder_memusage() returns UINT64_MAX if lc/lp/pb aren't valid. alone_decoder.c and lzip_decoder.c didn't check the return value because in both it is known that lc/lp/pb are valid. Make them call the _nocheck() variant instead which skips the validation (it already existed for LZMA2's internal use). Fixes: Coverity CID 464658 Fixes: Coverity CID 897069
