AMD IOMMU: use cmd_buf_size when freeing the command buffer
The command buffer release function uses the CMD_BUF_SIZE macro for get_order. Replace this with iommu->cmd_buf_size which is more reliable about the actual size of the buffer. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
