powerpc/pseries: Set UNISOLATE on dlpar_memory_remove_by_ic() error
As previously done in dlpar_cpu_remove() for CPUs, this patch changes
dlpar_memory_remove_by_ic() to unisolate the LMB DRC when the LMB is
failed to be removed. The hypervisor, seeing a LMB DRC that was supposed
to be removed being unisolated instead, can do error recovery on its
side.
This change is done in dlpar_memory_remove_by_ic() only because, as of
today, only QEMU is using this code path for error recovery (via the
PSERIES_HP_ELOG_ID_DRC_IC event). phyp treats it as a no-op.
