Paulo Alcantara 0a05ad21d7 smb: client: refresh referral without acquiring refpath_lock ...

Avoid refreshing DFS referral with refpath_lock acquired as the I/O
could block for a while due to a potentially disconnected or slow DFS
root server and then making other threads - that use same @server and
don't require a DFS root server - unable to make any progress.
