- Include upstream patches designated as stable material and
  reviewed for applicability to include here. NOTE that the
  PIIX4 patch has migration implications: the change will also be
  applied to the SLE-15-SP2 qemu, and a live migration from that
  version to this SLE-15-SP3 qemu would require this patch to be
  applied for a successful migration if PIIX4 southbridge is used
  in the machine emulation (x86 i440fx)

Subject: block/rbd: Fix memory leak in qemu_rbd_co_create_opts()
Git-commit: b084b420d9d6347dede328fbcf18c8e4c695f7e8
When we allocate 'q_namespace', we forgot to set 'has_q_namespace'
to true. This can cause several issues, including a memory leak,
since qapi_free_BlockdevCreateOptions() does not deallocate that
memory, as reported by valgrind:
13 bytes in 1 blocks are definitely lost in loss record 7 of 96

Fix setting 'has_q_namespace' to true when we allocate 'q_namespace'.
