[PATCH] lparstat: Use pool_capacity for determining active cpus in a pool

[Luciano Chavez]

commit efa87d93231eb0fe4f406bf58e7d5aa783ee4f13 introduced a change
in get_active_cpus_in_pool() that primarily used the value from the
physical_procs_allocated_to_virtualization sysentry to represent the
cpus active in a pool. This is incorrect as that value represents
the physical processors in the system allocated to virtualization.

This patch reverts the get_active_cpus_in_pool() function to only use
the pool_capacity sysentry for correctly determining the active cpus
in a pool.

Need a fixes tag as this was a regression introduced by a previous commit.
