NFS: Fix uninitialized rpc_wait_queue
Michael Sterrett reports a NULL pointer dereference on NFSv3 mounts when
CONFIG_NFS_V4 is not set because the NFS UOC rpc_wait_queue has not been
initialized. Move the initialization of the queue out of the CONFIG_NFS_V4
conditional setion.
Fixes: 7d6ddf88c4db ("NFS: Add an iocounter wait function for async RPC tasks")
