[CIFS] Fix cifs reconnection flags
In preparation for Jeff's big umount/mount fixes to remove the possibility of various races in cifs mount and linked list handling of sessions, sockets and tree connections, this patch cleans up some repetitive code in cifs_mount, and addresses a problem with ses->status and tcon->tidStatus in which we were overloading the "need_reconnect" state with other status in that field. So the "need_reconnect" flag has been broken out from those two state fields (need reconnect was not mutually exclusive from some of the other possible tid and ses states). In addition, a few exit cases in cifs_mount were cleaned up, and a problem with a tcon flag (for lease support) was not being set consistently for the 2nd mount of the same share CC: Jeff Layton <jlayton@redhat.com> CC: Shirish Pargaonkar <shirishp@us.ibm.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
