Browse source

[ Upstream commit 09e65ee905 ]

Otherwise the virtqueue object to instate could point to invalid address
that was unmapped from the MTT:

  mlx5_core 0000:41:04.2: mlx5_cmd_out_err:782:(pid 8321):
  CREATE_GENERAL_OBJECT(0xa00) op_mod(0xd) failed, status
  bad parameter(0x3), syndrome (0x5fa1c), err(-22)
