[PATCH] ath_hif_usb: don't oops if fw not found

[Helmut Schaa]

ath_hif_usb oopses when the firmware file cannot be found. Fix this by
reordering init_usb_anchor in hif_init_dev so that hif_dev->rx_submitted
is actually initialized when usb_poison_anchored_urbs gets called as a
result of the failed firmware request.

Luis, would you like the oops/backtrace in the commitmessage as well?
