ar9170: fix hang on stop
This patch fixes a locking problem which freezes the network core.
The deadlock goes as follows:
- ar9170_op_stop - is called
1. change the state to IDLE
2. > take the MUTEX <
3. cancel_SYNC all pending work, which means
"block until a work_struct's callback has terminated"
=> if filter_config_work was queued it tries to get the MUTEX,
before checking the device state...
