Fotis Panagiotopoulos 3c54d82d81 net: Fix task block when devif_send fails. 
When a task needs to send data, a callback is allocated and the
transmission is happening in a worker task through devif_send.
Synchronization between the two tasks (sender & worker) is
achieved by a semaphore.

If devif_send fails, this semaphore was never posted, leaving
the sending task blocked indefinitely. This commit fixes this
by checking the return code of netif_send, and posting this
semaphore in case of failure.

Polling then stops, and execution is resumed on the sending
task.
