125844eaff qlge: Move firmware event handler. 
This is not a logical change but rather a move of the inbound firmware event
handler into it's own function as it will later be called by the outbound
path.
The addition of the mutex is to create exclusive access to the mailbox
commands between inbound and outbound handling.

[ 2845.743742] Rebooting in 3 seconds..

My logitec bluetooth mouse trying connect to pc, but
pc side reject the connection again and again. then panic happens.

The reason is due to hci_conn_del_sysfs now called in hci_event_packet,
the del work is done in a workqueue, so it's possible done before
skb_queue_purge called.

I move the hci_conn_del_sysfs after skb_queue_purge just as that before
marcel's commit.

Remove the hci_conn_del_sysfs in hci_conn_hash_flush as well due to
hci_conn_del will deal with the work.

2526d3d8b2 Bluetooth: Permit BT_SECURITY also for L2CAP raw sockets 
Userspace pairing code can be simplified if it doesn't have to fall
back to using L2CAP_LM in the case of L2CAP raw sockets. This patch
allows the BT_SECURITY socket option to be used for these sockets.
