Vaibhav Jain 8f45abd50a powerpc/pseries: Skip vpa_init() for boot cpu in smp_setup_cpu() ...

During pSeries_setup_arch(), VPA for boot-cpu is first to be
initialized. However later in the boot, smp_setup_cpu() is called for
setting up VPA on boot and secondary cpus that were brought online. This
results in vpa_init() being called twice for boot-cpu and three redundant
H_REGISTER_VPA hcalls being made to the hypervisor.

Fix this by adding an extra condition in smp_set_cpu() to call vpa_init()
only on non boot-cpus.
