nfs: Use libihash for the node cache.

* nfs/cache.c: Remove old node cache and use libihash. Use a pointer to
the node handle as the key and the node itself as the value. Use
netfs_make_node_alloc to allow libihash to set 'slot'.
* nfs/nfs.c: Pass in a struct handle instead.
* nfs/nfs.h: Add a hurd_ihash_locp_t field and remove hnext and hprevp.
