md-cluster: use DLM_LSFL_SOFTIRQ for dlm_new_lockspace()

Browse Source 
Use the recently added DLM_LSFL_SOFTIRQ flag in dlm_new_lockspace(),
signalling the ability to handle callbacks being run from softirq
context.  The md-cluster callback functions only call complete(),
which is suitable for softirq.  This should make dlm lock request
completions more efficient by avoiding the workqueue context switch.
