cifs: change tcon status when need_reconnect is set on it

[ 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.
