IB/mlx4: Don't overwrite fast registration page list when posting work request
The low-level mlx4 driver modified the page-list addresses for fast
register work requests post send to big-endian, and set a "present"
bit. This caused problems later when the consumer attempted to unmap
the pages using the page-list (using the list addresses which were
assumed to be still in CPU-endian order). Fix the mlx4 driver to
allocate two buffers and use a private buffer for the hardware-format
bus addresses.
This patch fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1571>,
an NFS/RDMA server crash. The cause of the crash was found by Vu Pham
of Mellanox. The fix is along the lines suggested by Steve Wise in
comment #21 in bug 1571.
