Some cleanup of function postcopy_send_discard_bm_ram:

* use a more restrict check for discard page
* break the loop when no more page to discard
* it is for sure discard_length is not 0

No functional change.

Wei Yang (3):
  migration/postcopy: the valid condition is one less then end
  migration/postcopy: break the loop when there is no more page to
    discard
  migration/postcopy: discard_length must not be 0
