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

ehca2ib_return_code() is not used in any fast path, and making it
non-inline saves ~1.5K of code.

Instead of one error mapping function for each potential error source
in ehca_mrmw.c, use a centralized function that handles all cases,
saving a three-figure line count.

- ehca_cq.nr_events is made an atomic_t, eliminating a lot of locking.
- The CQ is removed from the CQ idr first now to make sure no more
completions are scheduled on that CQ. The "wait for all completions to
end" code becomes much simpler this way.

The eHCA driver does not compile for a uniprocessor configuration
(CONFIG_SMP=n), due to H_SUCCESS and other symbols being undefined.
This fixes it.
