guest_directory_close expected ENOTDIR from getdents on a descriptor number reused by a regular file, and guest_directory_buffer expected ENOTDIR for descriptor -1. kern_getdirentries returns EINVAL for a vnode that is not a directory and getvnode returns EBADF for a descriptor that is not open, which is what sceKernelGetdirentries now reports on Windows.
