fs: dlm: fix mismatch of plock results from userspace
When a waiting plock request (F_SETLKW) is sent to userspace for processing (dlm_controld), the result is returned at a later time. That result could be incorrectly matched to a different waiting request in cases where the owner field is the same (e.g. different threads in a process.) This is fixed by comparing all the properties in the request and reply. The results for non-waiting plock requests are now matched based on list order because the results are returned in the same order they were sent.
