[DLM] fix lost flags in stub replies
When the dlm fakes an unlock/cancel reply from a failed node using a stub
message struct, it wasn't setting the flags in the stub message. So, in
the process of receiving the fake message the lkb flags would be updated
and cleared from the zero flags in the message. The problem observed in
tests was the loss of the USER flag which caused the dlm to think a user
lock was a kernel lock and subsequently fail an assertion checking the
validity of the ast/callback field.
