Fix regression introduced by commit
214916f2ec6701e1c9972f26c60b3dc37d3153c6 (USB: visor: reimplement using
generic framework) which broke initialisation of UX50/TH55 devices that
used re-mapped bulk-out endpoint addresses.
Compile-only tested.

Hi Greg and Robert,
I missed the implications of the end-point remapping that was made for the
UX50/TH55 devices (write urbs are now initialised prior to attach). If Robert
confirms this patch solves the problem he's experiencing then this one should
go to stable as well.
Thanks,
Johan
