rt2x00usb: mark device removed when get ENOENT usb error

commit bfa62a52cad93686bb8d8171ea5288813248a7c6 upstream.

ENOENT usb error mean "specified interface or endpoint does not exist or
is not enabled". Mark device not present when we encounter this error
similar like we do with ENODEV error.

Otherwise we can have infinite loop in rt2x00usb_work_rxdone(), because
we remove and put again RX entries to the queue infinitely.

We can have similar situation when submit urb will fail all the time
with other error, so we need consider to limit number of entries
processed by rxdone work. But for now, since the patch fixes
reproducible soft lockup issue on single processor systems
and taken ENOENT error meaning, let apply this fix.

Patch adds additional ENOENT check not only in rx kick routine, but
also on other places where we check for ENODEV error.
