Zilin Guan 665077d78d vfio/pds: Fix memory leak in pds_vfio_dirty_enable() ...

pds_vfio_dirty_enable() allocates memory for region_info. If
interval_tree_iter_first() returns NULL, the function returns -EINVAL
immediately without freeing the allocated memory, causing a memory leak.

Fix this by jumping to the out_free_region_info label to ensure
region_info is freed.
