Subject: [PATCH 08/12] IB/ehca: Replace get_paca()->paca_index by the more portable raw_smp_processor_id()

We can use raw_smp_processor_id() here because the processor ID is only used
for debug output and may therefore be preemption-unsafe.

This is the same patch, but with smp_processor_id() replaced by
raw_smp_processor_id(), as kindly pointed out to me by Nathan. Thanks!
