Alexander Aring 7b57fc3f4c fs: dlm: fix mismatch of plock results from userspace
[ Upstream commit 57e2c2f2d94cfd551af91cedfa1af6d972487197 ]

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.
