nfsd: use an xarray to store v4.1 session slots

Using an xarray to store session slots will make it easier to change the
number of active slots based on demand, and removes an unnecessary
limit.

To achieve good throughput with a high-latency server it can be helpful
to have hundreds of concurrent writes, which means hundreds of slots.
So increase the limit to 2048 (twice what the Linux client will
currently use).  This limit is only a sanity check, not a hard limit.
