[ Upstream commit 0a05ad21d77a188d06481c36d6016805a881bcc0 ]
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.
