dlm: use more NOFS allocation
Change some GFP_KERNEL allocations to use either GFP_NOFS or ls_allocation (when available) which the fs sets to GFP_NOFS. The point is to prevent allocations from going back into the cluster fs in places where that might lead to deadlock. Signed-off-by: David Teigland <teigland@redhat.com>
