pNFS: Add a flag argument to pnfs_destroy_layouts_byclid()

Browse Source 
Change the bool argument to a flag so that we can add different modes
for doing bulk destroy of a layout. In particular, we will want the
ability to schedule return of all the layouts associated with a given
NFS server when it reboots.
