Before device_register, if something goes wrong, we need to manually
free idev.
In the error handling path, after device_unregister, idev maybe have been
released, we should not use it anymore.

Hi
I find it caused by below steps:
1. set tp_version to TPACKET_V3 and req->tp_block_nr to 1
2. set tp_block_nr to 0
Then pg_vec was freed, and we did not delete the timer?

Hi,
Do we need delete the v3 ring, when tp_version changed from TPACKET_V3 to
TPACKET_V1 ?
