[PATCH 24/28] powerpc/pseries/lparcfg: Use num_possible_cpus() for potential processors

The systemcfg processorCount variable tracks currently online variables,
not possible ones, so the stored value is wrong.
The code preferably tries to use the ibm,lrdr-capacity field 4 which
"represents the maximum number of processors that the guest can have."
Switch from processorCount to the better matching num_possible_cpus().
