liblzma: Silence warnings from clang -Wconditional-uninitialized.

This is similar to 2ce4f36f179a81d0c6e182a409f363df759d1ad0.
The actual initialization of the variables is done inside
mythread_sync() macro. Clang doesn't seem to see that
the initialization code inside the macro is always executed.
