NLM: Introduce external nlm_host set-up and tear-down functions
We would like to remove the per-lock-operation nlm_lookup_host() call from nlmclnt_proc(). The new architecture pins an nlm_host structure to each NFS client superblock that has the "lock" mount option set. The NFS client passes in the pinned nlm_host structure during each call to nlmclnt_proc(). NFS client unmount processing "puts" the nlm_host so it can be garbage- collected later. This patch introduces externally callable NLM functions that handle mount-time nlm_host set up and tear-down.
