NFS: Client side changes for RDMA

These patches are mostly cleanups and bugfixes for using RDMA as an
over-the-wire transport.

Highlights include:

- Remove obsolete memory registration modes.
- Removing BUG_ON()s to keep client's running.
- Fix deadlocks, NULL-pointer dereferences, and memory leaks.
