LU-2104 recovery: keep valid obd_stale_clients during recovery

- in class_fail_export() update obd_stale_clients counter if
  recovery is in progress. That fixes endless recovery issues.
- class_disconnect_stale_exports() should check exp_failed and
  exclude such exports from being evicted once more.
- set obd_no_conn flag in ofd_prepare() like mdt does.
- remove check for obd_no_conn from check_for_clients(). That is
  extra check as we don't allow any client to connect while
  obd_no_conn is set

LU-2360 ptlrpc: a few fixes for req_history read

This patch fixed a few issues in seq_file operations of ptlrpc
request history:
- start() function always start from CPT 0 despite of start position,
  this might cause endless read.
- ptlrpc history sequence can't be directly used as read position of
  seq_file, because seq_read() can increase position to indicate
  reading of the next element, this will actually change CPT ID of
  sequence, which means it's possible that next() will never be able
  to finish iteration of requests on a CPT in some case.
