NLM: Move the public declaration of nsm_unmonitor() to lockd.h
Clean up. Make the nlm_host argument "const," and move the public declaration to lockd.h. Add a documenting comment. Bruce observed that nsm_unmonitor()'s only caller doesn't care about its return code, so make nsm_unmonitor() return void. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.
