Pavel Shpakovskiy af181eb716 Bluetooth: hci_sync: fix set_local_name race condition 
[ Upstream commit 6bbd0d3f0c ]

Function set_name_sync() uses hdev->dev_name field to send
HCI_OP_WRITE_LOCAL_NAME command, but copying from data to hdev->dev_name
is called after mgmt cmd was queued, so it is possible that function
set_name_sync() will read old name value.

This change adds name as a parameter for function hci_update_name_sync()
to avoid race condition.
