[PATCH 14/20] perf util/lzma: close lzma stream

[Riccardo Mancini]

ASan reports memory leaks when running the perf test
"88: Check open filename arg using perf trace + vfs_getname".
One of these is caused by the lzma stream never being closed inside
lzma_decompress_to_file.

This patch adds the missing lzma_end.
