Si-Wei Liu ad89653f79 vhost-vdpa: fix page pinning leakage in error path (rework) ... Pinned pages are not properly accounted particularly when mapping error occurs on IOTLB update. Clean up dangling pinned pages for the error path. The memory usage for bookkeeping pinned pages is reverted to what it was before: only one single free page is needed. This helps reduce the host memory demand for VM with a large amount of memory, or in the situation where host is running short of free memory.
