add missing check of osmo_wqueue_enqueue() return value
The return value of osmo_wqueue_enqueue() isn't checked. This can result in a memory leak if the message cannot be enqueued. Log an error an free the message upon failure, as done elsewhere. Change-Id: I5671ca364f31d98f2b28d028e7bf1797386de2ec Related: CID#57662
