USB: add support for Motorola ROKR Z6 cellphone in mass storage mode
upstream commit: cc36bdd47ae51b66780b317c1fa519221f894405
Motorola ROKR Z6 cellphone has bugs in its USB, so it is impossible to use
it as mass storage. Patch describes new "unusual" USB device for it with
FIX_INQUIRY and FIX_CAPACITY flags and new BULK_IGNORE_TAG flag.
Last flag relaxes check for equality of bcs->Tag and us->tag in
usb_stor_Bulk_transport routine.
