[PATCH 3/5] spapr.c: add 'unplug already in progress' message for PHB un

Subject: [PATCH 3/5] spapr.c: add 'unplug already in progress' message for PHB unplug
Date: Fri, 26 Feb 2021 13:32:59 -0300

Both CPU hotunplug and PC_DIMM unplug reports an user warning,
mentioning that the hotunplug is in progress, if consecutive
'device_del' are issued in quick succession.

Do the same for PHBs in spapr_phb_unplug_request().
