update submodule and patches to 6.2.0

Notable changes:
* bdrv_co_p{discard,readv,writev,write_zeroes} function signatures
  changed, to using int64_t for offsets/bytes and some still had int
  rather than BrdvRequestFlags for the flags.
* job_cancel_sync now has a force parameter. Commit messages in
  73895f3838cd7fdaf185cf1dbc47be58844a966f
  4cfb3f05627ad82af473e7f7ae113c3884cd04e3
  sound like using force=true makes more sense.
* Added 3 patches coming in via qemu-stable tag, most important one is
  to work around a librbd issue.
* Added another 3 patches from qemu-devel to fix issue leading to
  crash when live migrating with iothread.
* cluster_size calculation helper changed (see patch pve/0026).
* QAPI's if conditionals now use 'CONFIG_FOO' rather than
  'defined(CONFIG_FOO)'
