Windows: SMB GetFileAttributes support

commit 56a2cbb5fbdcab51bd5f4720e610796abbce5c41 added a
GetFileAttributes query to the pioctl interface to protect
against printing pages on printers with a broken smb protocol
implementation.   This patchset adds support for GetFileAttribute
on _._AFS_IOCTL_._ files to the SMB implementation.
