qemu: Fix NULL pointer access in qemuProcessInitCpuAffinity()
Commit
2f2254c7f4e5 attempted to fix a memory leak by ensuring
cpumapToSet is always a freshly allocated bitmap, but regrettably
introduced a NULL pointer access while doing so, because it called
virBitmapCopy() without allocating the destination bitmap first.
Solve the issue by using virBitmapNewCopy() instead.
