    IB/qib: fix refcount leak in lkey/rkey validation



    The mr optimization introduced a reference count leak on an exception test.

    The lock/refcount manipulation is moved down and the problematic exception

    test now calls bail to insure that the lock is released.



    Additional fixes as suggested by Ralph Campbell <ralph.campbell at qlogic.org>:

    - reduce lock scope of dma regions

    - use explicit values on returns vs. automatic ret value
