perf lzma: Close lzma stream on exit 

[ Upstream commit f8cbb0f926ae1e1fb5f9e51614e5437560ed4039 ]

ASan reports memory leaks when running:

  # 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().
