Alan Stern e9238221d3 USB: dummy-hcd: accept mismatch between wLength and transfer length 
This patch (as1269) fixes a bug in the way dummy_hcd handles control
URBs.  Currently it returns a -EOVERFLOW error if the wLength value in
the setup packet is different from the URB's transfer_buffer_length.

Other host controller drivers don't do this.  There's no reason the
two length values have to be equal, and in fact they sometimes aren't
-- a driver might set the transfer length to the maxpacket value in
order to handle buggy devices that don't respect wLength.

This patch simply removes the unnecessary check and error return.
