RDMA/IPoIB: Add tx timeout work to recover queue stop situation

As we sometime run into TX timeout from IPoIB, queue seems stopped
and can't recover. Diff with Mellanox OFED show Mellanox driver
has timeout work to recover in such case.

Add TX timeout work/NAPI work to recover such case.

Also increase the watchdog_timeo to 10 seconds, so more tolerant to
error.
