fs: dlm: fix possible use after free if tracing
This patch fixes a possible use after free if tracing for the specific
event is enabled. To avoid the use after free we introduce a out_put
label like all other user lock specific requests and safe in a boolean
to do a put or not which depends on the execution path of
dlm_user_request().
