Here is the final patch of Aurelien's 4 patch series for improving
multichannel performance.  There is still some work to do (on
additional reconnect improvements e.g.) but the performance numbers in
my testing looked really good.

first steps in trying to make channels properly reconnect.

* add cifs_ses_find_chan() function to find the enclosing cifs_chan
  struct it belongs to
* while we have the session lock and are redoing negprot and
  sess.setup in smb2_reconnect() redo the binding of channels.
