ctdb-scripts: Initialise CTDB_NFS_CALLOUT in statd-callout

Browse Source 
Some configurations may set CTDB_NFS_CALLOUT to the empty string.
They may do this if they allow a choice of NFS implementations.  In
this case the default call-out for Linux kernel NFS should be used.
However, statd-callout does not call nfs_callout_init() to set the
default.  Therefore, statd-callout is unable to restart the lock
manager, so the grace period is never entered.

statd-callout must call nfs_callout_init() before trying to restart
the lock manager.
