[ Upstream commit c6e02eefd6ace3da3369c764f15429f5647056af ]
When a tcon is marked for need_reconnect, the intention is to have it reconnected.
This change adjusts tcon->status in cifs_tree_connect when need_reconnect is set. Also, this change has a minor correction in resetting need_reconnect on success. It makes sure that it is done with tc_lock held.
