Subject: NFSd: Move default initialisers from create_client() to
alloc_client()
From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
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.
