NFSd: Move default initialisers from create_client() to alloc_client()
commit 5694c93e6c4954fa9424c215f75eeb919bddad64 upstream.
Aside from making it clearer what is non-trivial in create_client(), it
also fixes a bug whereby we can call free_client() before idr_init()
has been called.

[bwh: Backported to 3.2:
- Adjust context
- Also move initialisation of nfs4_client::cl_strhash, but
not nfs4_client::cl_revoked]
