lockd: get rid of reference-counted NSM RPC clients
Currently we have reference-counted per-net NSM RPC client which created on the first monitor request and destroyed after the last unmonitor request. It's needed because RPC client need to know 'utsname()->nodename', but utsname() might be NULL when nsm_unmonitor() called. So instead of holding the rpc client we could just save nodename in struct nlm_host and pass it to the rpc_create(). Thus ther is no need in keeping rpc client until last unmonitor request. We could create separate RPC clients for each monitor/unmonitor requests. Signed-off-by: Andrey Ryabinin <aryabinin@virtuozzo.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
