Yang Yingliang 649cd16c43 media: flexcop-usb: fix NULL-ptr deref in flexcop_usb_transfer_init() 
If usb_set_interface() failed, iface->cur_altsetting will
not be assigned and it will be used in flexcop_usb_transfer_init()
It may lead a NULL pointer dereference.

Check usb_set_interface() return value in flexcop_usb_init()
and return failed to avoid using this NULL pointer.
