  has CONFIG_BRANCH_PROFILE_NONE enabled and make it similar
  to riscv, x86 and also to commit 4bf3ec384edf ("s390: disable
  branch profiling for vdso").

- Currently, if the device is offline and all the channel paths are
  either configured or varied offline, the associated subchannel gets
  unregistered. Don't unregister the subchannel, instead unregister
  offline device.
