NSM: Move nsm_find() to fs/lockd/mon.c
The nsm_find() function sets up fresh nsm_handle entries. This is
where we will store the "priv" cookie used to lookup nsm_handles during
reboot recovery. The cookie will be constructed when nsm_find()
creates a new nsm_handle.
As much as possible, I would like to keep everything that handles a
"priv" cookie in fs/lockd/mon.c so that all the smarts are in one
source file. That organization should make it pretty simple to see how
all this works.
To me, it makes more sense than the current arrangement to keep
nsm_find() with nsm_monitor() and nsm_unmonitor().
So, start reorganizing by moving nsm_find() into fs/lockd/mon.c. The
nsm_release() function comes along too, since it shares the nsm_lock
global variable.
