Mike Marciniszyn 8aac4cc3a9 IB/qib: RCU locking for MR validation
Profiling indicates that MR validation locking is expensive.  The MR
table is largely read-only and is a suitable candidate for RCU locking.

The patch uses RCU locking during validation to eliminate one
lock/unlock during that validation.
