fuse_perm_getattr() requests only STATX_MODE | STATX_UID | STATX_GID. fi->i_time is only advanced when the response covers STATX_BASIC_STATS in full, so a perm-only refresh clears the perm bits from inval_mask but leaves i_time at its old (expired) value. Add fi->i_perm_time, updated whenever a refresh covers MODE|UID|GID (always for the non-statx getattr path; conditionally on returned_attrs for the statx path), and gate fuse_permission()'s sync decision on it instead of i_time. fuse_update_get_attr() continues to use i_time so a full stat() still re-queries the server when size/mtime/etc. expire.
