Dhananjay Phadke b2af9cb06d netxen: fix deadlock on dev close 
netxen: fix deadlock on dev close

The tx ring accounting fix in commit cb2107be43
("netxen: fix tx ring accounting") introduced intermittent
deadlock when inteface is going down.

This was possibly combined effect of speculative tx pause,
calling netif_tx_lock instead of queue lock and unclean
synchronization with napi which could end up unmasking
interrupt.
